There are some fights you just can't win. A force can be so overwhelming that no tactical approach in a fight is going to lead to a victory worth having. When you can't win in a fight, sometimes you have to settle for making sure that if you lose, everyone loses. It works for nuclear weapons; it works for me.

Most people think distracting a group of guys is best done by a beautiful woman. The problem with beautiful women is people want them to stick around, which can cause a lot of problems. Obnoxious guys, they just want to get rid of.

Security

The thing about security is that the very things that protect you can be turned against you by someone who knows what he's doing. It's tough to compromise a well thought-out security system, but making someone think you can compromise it, well, that's much easier. Take surveillance cameras, for example: you can disable one by shooting a laser at it and overloading the light sensitive chip. Cheap, easy, and exactly the sort of thing a sophisticated criminal gang with lots of resources would do. Leave around some tell-tale signs of surveillance like cigarette butts, a forgotten camera lens cap and the more security there is, the more likely they are to think they've got a very serious problem. Even the security team itself can be an opportunity. The more employees you have, the more you have to worry about them. Deliver some vague threats and a few hundred bucks to a security guard. If he's honest he'll tell his boss, who then wonders who wasn't so honest. For the cost of a nice dinner you can get a whole security team canned.
