My family comes first. As a warning, I would call 911 and tell the police I fear for my sons' lives and my life. Load a shotgun with #6 shot (5 rounds+ 1 in chamber) open door, warn, present, and aim. (911 tapes will show you feared for your life, police did not show up and you defended yourself and family). Anybody approaching the house should be shot. This is a riot situation and should not be tolerated. The police may detain you, but a lot of explaining would have to be done by DC PD and SEIU thuggery (how did they get the address and who was in the rent-a-mob). A man defending his family from 500 protesters is easy to defend and hard to prosecute.
