"He who does not think himself worth saving from poverty and ignorance by his own efforts, will hardly be thought worth the efforts of anybody else." -- Frederick Douglass, Self-Made Men (1872)
Policing and the military are wholly incompatible. The police job is to enforce laws, arrest alleged criminals and let the justice system sort things out. The military's job is to kill the enemy. The police are supposed to be part of the community in which they work they aren't supposed to act as an occupying army.
Arming the police as if they were the military and giving them military style training is a disaster waiting happen - or in truth that is already happening
Quo usque tandem abutere, Trump, patientia nostra?
There is nothing wrong with having more heavily armed police for extreme situations like the north hollywood shootout, but only if they are used in actual extreme situations. Instead, we have seen every wannabe Sheriff in the country treating this stuff like toys.
The police don't need it. And shoot, most of this stuff has never really been used. It was built despite our military not needing. Because NOT building it means laying off union manufacturing employees.
Learn to military industrial complex, guys.
It is not that they couldn't drive it just that it is a huge unwieldy vehicle with horrible blind spots. They are also horribly expensive to operate. Take it from someone who has spent a fair amount of time in one. No cop is going to want to drive around in one of these day in and day out. Hell they are to big to fit in parking spaces. Not to mention local citizens will get tired of it real quick.
President Franklin Roosevelt eulogized a fallen American Soldier by saying, “He stands in the unbroken line of patriots who have dared to die [that] freedom might live, and grow, and increase its blessings. Freedom lives, and through it he lives--in a way that humbles the undertakings of most men."
Oh, and let's not forget...owning and not using it is also pretty expensive. Stuff not in use (but ready for use) must be maintained. $$$
