Suburban cop clash caught on video

Tensions rise around the 3:30 mark, when Darby Borough police Chief Bob Smythe arrives on the scene and gets tangled up with a Colwyn cop. The Delaware County District Attorney's Offfice is investigating the incident, which occurred Friday.

I don't know if there's any evidence of an assault here. But it doesn't look good for neighboring police departments to be feuding. That part of the county has enough problems already. Your thoughts?
