When people do something wrong, they are often said to have "committed" an act. A person can "commit murder", "commit an armed robbery" or "commit a kidnapping", but I've never heard anyone say "commit a rescue" or "commit a birthday party".
Which makes me think I will specify that all acts of cop are "committed". Cops will "commit an arrest", "commit enforcement", or "commit a traffic stop" because those acts are bad, and cops are bad guys. It makes perfect sense to me.
