While much of the military hardware at the disposal of LAUSD police officers – including the 20-foot-long, 14-ton armored transport vehicles, much like the ones used to move Marines in Iraq combat zones – has never been used, Zipperman defended the decision to hang on to the MRAP.

“It is a vehicle that is available for a rescue in the event of a catastrophic incident that may occur within our region,” said Zipperman. “I believe it’s better to have some type of rescue vehicle than none at all.”

Valued at over $730,000, the armored vehicle was given to the LAUSD at no cost from the U.S. government.

LA Unified is among at least 22 school systems across eight states that have received surplus military equipment, The Los Angeles Times reported.
