Dr. William Petit, whose wife and two daughters were killed by two career criminals in Cheshire, CT, last year, has become an activist for the “Three Strike Law.” The law would five a mandatory life sentence on anyone convicted for the third time for a violent felony.

Petit’s wife and youngest daughter were raped. The mother was strangled to death and the two girls were tied in their beds and left to die when the two invaders set the house on fire.

ABC’s Good Morning America brought on a home defense “expert” who suggested that wind chimes and cactus on the windowsill would deter invaders.

UPDATE: From a commenter:

If cactus was actually effective at stopping malefactors, CT and MA would’ve required a license to buy, sell, and transport it long ago.
