It turns out there’s a downside to setting up a bomb factory in your house.

A man’s arms were blown off by an explosion at a property that had allegedly been stuffed with an arsenal of guns, ammunition and bombs.

Oops.

The victim, who is in his 30s, was reportedly left in critical condition after the blast at around 3:10 p.m. in Warren, Michigan, on Saturday, June 11.

The explosion ripped apart the garage with a subsequent fire engulfing other parts of the house on the 20700 block of Gentner Street, Warren Police Commissioner William Dwyer said.

It’s almost as if all this playing terrorist nonsense is a danger to other people as well as the bomb-maker they-self. I daresay the neighbors aren’t enormously pleased.

The man, who Dwyer said was already under investigation before the explosion, is now in a coma and undergoing treatment at the Detroit Receiving Hospital.

He has a long criminal history, involving weapons charges and manufacturing explosive items, according to Dwyer, who alleged that an illegal weapons operation was being run from the property.

He was defending our freedom.

After the blast, police executed a search warrant and found small explosive devices, a dozen guns, including rifles and handguns, loaded automatic rifle-style magazines, and about 4,000 rounds of ammunition, according to The Detroit News.

Just the basics.
