Should police be militarized

In some places, they already are. For example, in the military (army, navy, etc), they have their own police force. Also, in some countries where there is a Dictatorship, the army is in charge of all law enforcement, at the command of the leader of the country. This means law enforcement is arbitrary-- if the leader likes you, all is well; if the leader disagrees with your views, you can be arrested and detained.

That is one reason why many people prefer an independent local police force, rather than a nationalized military force. Local police are responsible to that community; they know the people and they know the issues. They can be very effective in enforcing the law, and at their best, they can keep a community safe without taking away people's rights.
