The Militarization of City Bylaw Officers?

I've been hearing a few concerns about the "militarization" of the city hall's bylaws department. At the very least, there is some feeling that we should not be replacing the RCMP with bylaw's officers. Bylaw officers currently sport bullet proof (knife proof?) vests emblazoned with the words PEACE OFFICER - and I have heard they may carry handcuffs.

Are these overkill? Are they necessary to do the job in today's times? Are bylaw officers trained in arresting and handcuffing folks? Do Rambo looking bylaw officers unnecessarily scare people or send a message that is too strong?Question to research and ponder.
