Here's something I have a real problem with in this story. The police arrested BOTH of the men until they could get things sorted out, as they said. Am I missing something here? I mean, a bank with tellers and other employees. These are called witnesses who one might think that as soon as they saw the police arrive they would tell them who the bad guy was and that the man with the gun was a good guy.
I might understand why the police may want to do this (really I don't) if they came upon a scene where the only two people were the BG and the GG. Yeah, I know... they will use the excuse that, "we don't know who is who". But come on. Cops are pretty darned good at determining who the good guys and bad guys are up front. Granted, they don't want to take chance, but if I am out there holding someone under my gun and the cops arrive, I am going to carefully put my gun down and step away from it if asked to do so. I do not expect to be arrested, even for a moment.
If I am wrong in any of this, please educate me.
