This has been investigated and discussed, and it seems this post was about specifically something that happened a few days ago - which was dealt with a few days ago when it happened. So unless anything has happened recently then this is unnecessary to look into this any further.
I would also like to discourage this kind of accusation, according to who I've spoken to - this happened a few times the first day he was a cop, and was dealt with very clearly that day, and hasn't happened since. Specifically a post with no actual account of any specific incident or evidence but just a giant assumption that something is going on by inferences made by someone.
Anyway, I hope this helps. If you have any other questions feel free to ask
*edit*
I'd also like to add that you stating that the reason he has so many arrests is just because he cheats is certainly not true. If there were over 200 cases of someone planting drugs it would have been stopped a long time ago, people asserting this are either stupid or mad. Not sure which.
