While I have zero info on the "raid," it is NOT at all uncommon for a particular individual of "interest" to have a target placed on their back. This story sounds "possible" to me.
Black dude / white police chief?
Any dude who hooks up with the chiefs daughter?
Anyone with any political interest whatsoever?
BOOM! You now have a target on your back for any little thing.
As far as resources go, it's not coming out of the police chief's pocket. There's a war on drugs I see being pushed on tv everyday. Easily justifiable to the DA who probably gets drunk with the chief in a small town on the weekends...
Lower charge than expected for xanax? Multiple reasons that could happen. Shitty warrant served, cops know it will get tossed out in court, so they plea a deal with the guy for a simple misdemeanor... Shit I've seen RAPE reduced to endangering the welfare of a CHILD under 10 years old. Fucked up, but it is actually a normal practice in prosecution techniques. They would rather get him on something small than risk losing against something big. DA wants a 100% success rate in prosecutions for their next election too remember.
Don't be too careful. Piss off the wrong police chief and like any other guy they can want to simply FUCK YOU. Don't ever be too careful. And you better be damn sure MULTIPLE LE agencies are looking at this thread every minute.
