To be fair, that pic really is just an SUV with some extra plating... nothing you as an average citizen couldn't whip up perfectly legally in your garage.
Just because it looks military, doesn't make it so. After all, that's what we're fighting the gun control industry about right now isn't it?
There is a line that is constantly being drawn between how 'military' the police should be. Post 9/11 that line has shifted to the point where (supposedly) the NYPD has surface-to-air missiles at their disposal. To me that's probably too far, but you can certainly debate it.
Certainly protective vehicles and gear, select-fire firearms, etc. all fit well within the scope of police activities. However I don't think that they should be limited to police only.
If police are allowed a certain type of equipment, there is no reason that non-LE citizens should be denied that same piece of equipment. After all, police are simply regular citizens that we authorize to act on our behalf by granting them 'police powers'.
They are citizens who have accepted extra duties, extra responsibilities and restrictions on their behavior, but that does not mean they have constitutional rights that are any different than other citizens.
A police officers ability to have any type of weapon is based on their Second Amendment rights as a citizen, not on their additional duties as a police officer.
I would say that the if LE has the ability to have weapons that the average civilian can not (something I am not aware of, BTW) all it means is that their 2nd Amendment rights are simply less infringed upon than ours have been.
