Cops now face the probablity (although still low) of facing a mass shooter and we want them not to have MRAPs? They’re mine resistance is only a coincidence. The bottom line is that they’re available for free to LE departments. Getting a free MRAP is a lot cheaper than buying an off the shelf armored vehicle. The existence of MRAP and LE departments do not change or create laws. And again, they’re rarely used.
