This would me far more ideal but far less likely at the same time-unless you live in certain urban war zones...

One certain way of defending against a well equipped team of urban marauders is a neighborhood wide defense; if they come in with seemingly overwhelming numbers you have at least one or two people to raise the alarm-a phone tree or even do a Paul Revere with a whistle or bell.

Every house in the neighborhood that has watchmen will have rifle-proof shooting positions at positions far from the windows. These ballistic barriers can be camoflaged inside cabinets and such. Watchmen will have what high powered rifles at the ready. Certain locations may have more...

Wherever the raid goes neighborhood watchmen on standby grab their rifles and get into the proper positions. As the urban marauders step out they take random gunfire from multiple angles as they form up for a home invasion. If other weapons are available they would be used of course. The marauders may have additional reinforcements in a perimeter encircling the targeted home and may rush to the rescue. If they remain on station the person whose house is being raided has a better chance of escaping. He's lost that home anyway.

Always shoot at the criminal with the scoped rifle first!

This sadly requires several people in your neighborhood to be ready at all times to repel intruders, because you'd never have your full neighborhood watch group around... got to work, shop.
