It is of course trivially easy to plant something with or without bodycams. And even if it were impossible, police could simply charge you for running a stop sign, running a red light, using your phone while driving, dangerous driving, or a hundred other things where bodycams are useless. More surveillance is never the answer, which is why even the NSA have admitted that mass surveillance has never prevented a single terrorist attack.

Note the bounty no longer exists.

The bounty eventually evolved to cover either Monero or Lightning transactions. It was awarded to Chainalysis in September of 2021, just before they publicly announced their "transaction monitoring solution" for Lightning (https://www.chainalysis.com/blog/lightning-network-support/).

So in other words the Monero bounty was unclaimed, and Chainalysis were awarded the money for instead offering the US government Lightning monitoring services.
