I was a cop for 30 years, the SWAT commander (extensive training & experience) and a gunfight survivor but now I'm a 70 y/o who walks w/a cane and I WOULD NOT "clear" my house in an emergency. I'd call 911 and wait in the locked bedroom w/my wife (just the two of us now) until the real cops showed up. My home protection weapon is a Glock 17.
