He destroyed ED 209.
Quite. He did destroy ED 209, but that was within reasonable force to uphold the law. Provided that the Terminator doesn't go blasting folks left and right, and endangering random people with automatic gunfire, Robocop could really only attempt to apprehend. When the Terminator resisted arrest enough to allow for destruction, it would probably be too late for Ol' Murphypants.
Read my set-up. I said the T800 killed police officers.
Whoops. Still, Robocop isn't from whenever the hell in the future the Terminator is. I think the technology is the deciding factor and by that, the Terminator wins. Barely.
