Concur. The use of a bomb strapped to a robot just escalated this situation by an order of magnitude. Mark my words, within 3 months some one is going to retaliate with a bomb of their own used against the para-military. I used to call them Law Enforcement, but that mission caught tossed aside when they became an instrument of the executive branch and DHS. Today they are a bunch of Ranger/Rambo wannabees armed to the teeth by a Federal government that sees the citizen as the enemy.
I am sad that as a citizen I don't trust my government nor the police any longer.
