Boston police are clashing with the city's incoming mayor over a proposal to arm some officers with AR-15 rifles.

The Boston Police Department had been pushing for a limited number of officers to carry the high-powered rifles, in light of recent mass shootings as well as the Boston Marathon bombing earlier this year, said Fox News. However, Mayor-elect Martin Walsh reportedly came out against the plan.

Under the plan, according to MyFoxBoston.com, the city would buy 33 AR-15 rifles, at $2,500 apiece. They would go to two trained officers in all 11 districts of Boston. 

But the plan needs the mayor's sign-off, said Fox News.

"I don't believe arming them with assault weapons is going to make them any safer," City Councilor Charles Yancey said, according to MyFoxBoston.com.
