If you're against paid administrative leave in this circumstance, then you are either

A) Against it in all circumstances, including those where it is obvious no wrongdoing occurred and the subject will be exonerated, or

Given you're apparently unaware this process is the standard for any unionized workplace, it seems likely that you just have some ideological beef with the police, and see police unions as an extension of the police rather than a union protecting its workers. If you're against collective bargaining, you're against job protections such as requiring investigation and cause for dismissal.

Lol He's obviously the cops union rep or close buddy. Who the fuck defends a thieving cop without some personal connection.
