McDONALD, Justice.

We accepted jurisdiction in this cause because the per curiam affirmance by the district court indicated contrary authority. We have jurisdiction pursuant to article V, section 3(b)(3) of the state constitution.

Earl Sidney Jefferson was shot and killed in a bar by a fellow patron. Stevens owned and operated the bar. Jefferson's widow alleged and proved that previously there had been numerous shootings and fights in the bar, that the owner had failed to train or equip employees to maintain order, and that no security personnel had been employed when the owner knew or should have known that his patrons were being exposed to risk of harm from fights or shootings by other patrons. In effect Mrs. Jefferson showed that Stevens either created a dangerous condition or allowed one to exist by the manner in which he ran his establishment. She did not allege, however, that Stevens knew of any dangerous propensities of Jefferson's assailant, and Stevens contends that Jefferson cannot prevail because of that lack of knowledge. We disagree.

The proprietor of a place of public entertainment owes his invitee a duty to use due care to maintain his premises in a reasonably safe condition commensurate with the activities conducted thereon. Central Theatres, Inc. v. Wilkinson, 154 Fla. 589, 18 So.2d 755 (1944). We have stated that the proprietor of a liquor saloon, although not an insurer of his patrons' safety, is bound to use every reasonable effort to maintain order among his patrons, employees, or those who come upon the premises and are likely to produce disorder to the injury or inconvenience of patrons lawfully in his place of business. Miracle v. Kriens, 160 Fla. 48, 33 So.2d 644 (1948). A determination as to whether this duty has been violated will, of necessity, depend upon a review of the facts of each individual case. Additionally, the risk of harm must be foreseeable. This foreseeability requirement has often been met by proving that the proprietor knew or should have known of the dangerous propensities of a particular patron. See, e.g., Sabatelli v. Omni International Hotels, Inc., 379 So.2d 444 (Fla. 3d DCA 1980). But specific knowledge of a dangerous individual is not the exclusive method of proving foreseeability. It can be shown by proving that a proprietor knew or should have known of a dangerous condition on his premises that was likely to cause harm to a patron. Fernandez v. Miami Jai Alai, Inc., 386 So.2d 4 (Fla. 3d DCA 1980).

To affix liability against a tavern owner for injuries to patrons intentionally inflicted by third parties, a risk of harm to his patrons must be reasonably foreseeable, and the weight of authority, both in this state and elsewhere, supports a standard of reasonable foreseeability. See, e.g., Sparks v. Ober, 192 So.2d 81 (Fla. 3d DCA 1966); Industrial Park Businessmen's Club, Inc. v. Buck, 252 Ark. 513, 479 S.W.2d 842 (1972); Kerby v. Flamingo Club, Inc., 35 Colo. App. 127, 532 P.2d 975 (1974); Gorby v. Yeomans, 4 Mich. App. 339, 144 N.W.2d 837 (1966); Tyrrell v. Quigley, 186 Misc. 972, 60 N.Y.S.2d 821 (N.Y. Sup. Ct. 1946); Waldron v. Hammond, 71 Wn.2d 361, 428 P.2d 589 (1967). Although knowledge of a particular assailant's propensity for violence is often found to be evidence of foreseeability in these cases, we reject the contention advanced by amicus curiae here that proof of foreseeability should be limited by law to evidence of actual or constructive knowledge of a particular assailant's propensity for violence. A tavern owner's actual or constructive knowledge, based upon past experience, that there is a likelihood of disorderly conduct by third persons in general which may endanger the safety of his patrons is also sufficient to establish foreseeability. Kerby v. Flamingo Club, Inc.; Tyrrell v. Quigley; Restatement (Second) of Torts § 344 comment f (1965).

Although stated in a different factual context, the Fourth District Court of Appeal in Crislip v. Holland, 401 So.2d 1115, 1117 (Fla. 4th DCA 1981), correctly summarized the law when it said:

An action for negligence is predicated upon the existence of a legal duty owed by the defendant to protect the plaintiff from an unreasonable risk of harm. The extent of the defendant's duty is circumscribed by the scope of the anticipated risks to which the defendant exposes others. In order to prevail in a lawsuit, the plaintiff must demonstrate that he is within the zone of risks that are reasonably foreseeable by the defendant. The liability of the tortfeasor does not depend upon whether his negligent acts were the direct cause of the plaintiff's injuries, as long as the injuries incurred were the reasonably foreseeable consequences of the tortfeasor's conduct. Concord Florida, Inc. v. Lewin, 341 So.2d 242 (Fla. 3rd DCA 1976). If the harm that occurs is within the scope of danger created by the defendant's negligent conduct, then such harm is a reasonably foreseeable consequence of the negligence. The question of foreseeability and whether an intervening cause is foreseeable is for the trier of fact. Gibson v. Avis Rent-A-Car System, 386 So.2d 520 (Fla. 1980).

(Emphasis in original.)

It is incumbent upon the plaintiff to prove legal causation. Warner v. Florida Jai Alai, Inc., 221 So.2d 777 (Fla. 4th DCA 1969), cert. discharged, 235 So.2d 294 (Fla. 1970). Mrs. Jefferson met her burden by showing that the bar was a "rough" place with a history of fights and gunplay and that the owner had terminated all security service and had left the premises in the charge of a female employee who could not maintain order. Under these facts a jury could determine that a foreseeable risk of harm to patrons existed, that the risk was either created or tolerated by Stevens, that he could have remedied the danger but failed to do so, and that because of that failure to perform his duties Jefferson was killed. The district court properly affirmed the judgment for Mrs. Jefferson and its action in doing so is approved.

It is so ordered.
