Well what do you hire a body guard for if not to protect your person so you don't have to do it yourself.

He approached our mayor with one of those big sodas that bloomers wants to out law.

If I was his body guard that tells me the guy may have been a little crazy.

You don't just let anybody approach the guy your guarding you get in the way and question him first. You might even frisk him while your talking to him.

Then you tell him go away and don't come back. Then if you see them again later anywhere you man is standing. Then you act. How's that sound?
