I've had people try this kind of stuff at my events before (granted, the ones at mine seemed more earnestly well-intentioned about it, even if still very misguided). Not only is it disruptive (I understand the argument of "open world RP" and I like spontaneity, but you have to understand that there is a schedule in place for these events, and people go to a date auction for date auction RP, they go to a rolling combat event to do/spectate combat RP with rolls, etc.), but people are rarely fully prepared to accept the IC fall out. People are going to hate and shun your character. People will attack and try to kill/arrest your character. People would report the incident to grand companies, and you'd realistically have NPC's on the lookout for your character. It never fails that they underestimate the amount of people who are going to dogpile onto their characters with weapons. And, then there's of course naturally no believable escape, so they always magically "teleport" away somehow.
So my two cents: Don't do it, and prepare to say goodbye to your character if you do.
