My brothers home got raided in mid December of 2010, the found a half of an ounce of marijuana and 3 grams of cocaine. I believe he sold to a undercover officer. He cooperated and gave up a person that was believed to have cocaine in his house hold but the police only found 2 firearms an X amount of marijuana and money. The police let my brother go under the understanding that he would have to help them make 2 additional arrest or they will pursue the charges against him. They made him sign sone paperwork and let him go. This all happened in Illinois. What can he do? Can the police do this? .The police officer that purchased the cocaine was a Joliet officer while my brother lived in crest hill.
