"How to defend against a home invasion in DC..."
Sounds like it's time to post this again: You respond by performing the SNiVeL maneuver as outlined below:
Step 1: "S" is for Safe - Assume a safe, fetal position, preferably under a table or other cover.
Step 2: "N" & "V" are for Non-Violent - Remember, remain non-violent. Moves that could be interpreted as 'self-defense' may only serve to further provoke your assailant. Offer no resistance.
Step 3: "L" is for Limp - Remain limp while begging and groveling for your life! This is no time for pride or courage, so cry like a girl, you fool! This will always serve you better than a firearm, which would only inject more violence into the situation. Finally, stay limp until your assailant has finished beating you like a rented mule. He will eventually tire from pummeling you mercilessly and choose to move on to a more entertaining endeavor, such as beating your spouse and/or children.
After the attack, you can evaluate how well this proven technique worked for you.
