Charging versus convicting
[QUOTE=ChefPablo40;6867376]First, in order to charge us we would have to be in the bedroom at the time they raided the apartment. [/QUOTE]Nope.
The police can arrest you based on the officer's suspicion, which is an ordeal all by itself. And since they can legally lie like a rug to lower your guard, "suspicious" is up to the officer to interpret. The prosecutor has discretion to charge you, and that's usually based on how likely a conviction or plea is. Prosecutors no longer care about justice, if they ever did. They care about convictions. Their goal these days seems to be to make the process so arduous and harmful that the defendant will just try to plead out. That way, the prosecutor gets credit for a conviction, the state / county / city gets the revenue, and the arrestee gets his mug shot plastered on the web, along with potential job and societal consequences. And if they [i[do [/i]elect to let you go, the arrest still stands in the record unless your lawyer is good enough to get it expunged.
The rest of your post was pretty spot on, especially the SHUT THE FUCK UP part. Every criminal lawyer will tell you that. No matter what you say to a cop, it'll be interpreted in the most negative and harmful (to you) possible way.
