I hope you are wrong. For one guy to be doing this in the manner it has been done, it would have to be a "Mack Bolan" type, and if that is the case, we are screwed, unless we go to martial law & suspend the constitution.
Of course, MB would be using a .460 Weatherby & be shooting mob guys.
Everything we post here is pure speculation, based on what we're told... I just happen to believe, given what I read and learn from the shootings, that they are two. I even believe that they are very young (late teens, early adults), but if they indeed arrested a "man", then I'm already wrong about that one...
