If you would ask this question in my country, if the police was so heavily armed then I would have had said yes. But in the US I do not think that is true. While the use of swat or heavily armed officers has gone a bit too far, if you live in a country where every Tom, Dick, Harry, Susy, Mary or Linda can be armed to the teeth, then you have no sense of real security as an officer.
I can still remember that heavily armed robbers had a 44 minute shootout with the police, if criminals are that heavily armed, it is not strange that the police will want to have, at least a few officers, that are equally if not better armed than the criminals they face.
If the question had been, are militarily armed officers used too often, then I would have voted yes.
