> Can a civilian buy an MRAP? If so, I think your argument works very well Yes you can if you found one for sale (not sure what that market looks like). Civilians can also buy decommissioned tanks, Two ton trucks, humvees, etc.
In that case, I'm definitely convinced to your side of the argument! If a civilian can buy it, I see no reason why a police force shouldn't be able to as well. That said, I'd love to hear any counter-arguments to this notion, if they exist.
My point, is these were given to the police. While a civilian may technically be eligible to buy one for $500k (bulk pricing) but we realistically have no opportunity to purchase. So the parent's comment applies.
