No, don't call the cops. There's no situation cops can't make worse. Talk to them yourself.
How naive.
If they're this uncaring or downright sociopathic about other people, there's very little chance they can actually be reasoned with and a near 100% chance that they'll now associate every police call or other complaint made about them to be attributable to you, and will retaliate.
TC, absolutely call the cops on them.
