In 1998 I was arrested after my home was raided by DEA and FBI for purchasing 500 ecstasy pills from an informant. I was bailed out the next day and placed on federal house arrest. I "cooperated" with the DEA. All I did was meet up with a DEA agent one time with my attorney and tell him everything I've ever bought and sold and who I bought it from. I never heard back from the Feds or DEA after that meeting.
I ended up getting off of house arrest after a little over a year later, which was still pretrial. My lawyer contacted the federal prosecutors office and got me off house arrest somehow.
Now, it's 2013 and I still haven't heard anything about the case. I know I don't have warrants out for my arrest as I've been pulled over for traffic violations and gone to court for them recently.
