Tough to watch........totally surprised, overwhelmed w sudden violence, trying not to enrage these goofballs and make it more dangerous for the family by offering resistance.
1. totally surprised. Get a dog. Big dog out side provides a partial deterrent and an early alarm, though easily overcome w poisoned food. Small inside dogs are usually great early warnings that are not as easily countered because, well, they're inside. Even if your alarm is not monitored, have it set to go off when doors are opened. Put up "this home monitored by xyz Alarm co" sign in yard, and stickers in windows. Even if it ain't, most thugs will move on to easier pickin's.
2. overwhelmed w sudden violence. Mindset. Be ready to administer unrelenting violence upon those who'd enter your domicile seeking to do you harm. Have NO doubts. Play enough realistic 'what ifs' to begin to formulate a plan, then try out the plan, amend it as needed, then practice it. All that being said, a complete blindside attack will be tough to ever get on the + side of the power curve.
3. trying not to enrage these goofballs and make it more dangerous. That's gonna really be an individual call. I've said it before when we talk about armed robberies at WH, restaurants, etc. If it's a pro team, chances are great that a) they are there for money, goods, etc, and don't really want a murder pinned on them, b) they are more practiced at this than most of us are at singlehandedly dealing w an armed, pro team. If that's the case, maybe, maybe it's more to your advantage, especially if totally in shock from the onset, to let them get the cash, gold, whatever and get out.....MAYBE. If it's a 'three stooges' hold up, and you can regain composure, and have ready access (carry at home?), being quick and determined might get you thro the night. In the video presented, the wife/daughter present really great leverage for the thugs over the husband/father. He's in a ******* spot.
If we're gonna play "What would you do" here, lemme think about it, and I'll try to post my thoughts in a few.
