But so that we may not cause offense, go to the lake and throw out your line. Take the first fish you catch; open its mouth and you will find a four-drachma coin. Take it and give it to them for my tax and yours."
Giving needless offense and causing a needless confrontation is foolish (secularists, which nearly all of the contestants probably were, should still heed Mt. 17:27). As Nota Bene pointed out, needless offense also directly entices others to sin, which is sinful itself.
In the end, it does not matter how skilled one is at arms*, or whether or not one "won" an avoidable confrontation on a particular occasion.
* Speaking of skill with arms, the firefight was over in 15 seconds with both assault weapon type shooters KIA. No wild shooting and with one exception, no other people even injured. That demonstrates alot of skill. The security guards that I saw in photos looked far more "Blackwater" than ordinary guards or moonlighting PD. My guess is that the orgainizers knew to bring some "ringers".
