From the way I understand it...
Cops show up for noise complaint - music is turned down, and as the cops are leaving, they turn the music right back up. Cops walk back up and tell them to turn it down again. Cops leave. No charges filed
Cops are called back to the location due to a fight, cops state about 90 people at the party with several underage.
Sapp is arrested as the home owner for supplying booze & Marijuana to the people at the party and underage people as well - As Sapp is attempting to be handcuffed, he kept resisting and attempting to pull away from the officer. AJ, notices his friend struggling, and grabs the cops shoulder and pulls him away from Sapp. Cops tackle Sapp, who is still resisting, and get him in cuffs.
AJ, lets go of the cop, and attempts to leave the location. But, is tackled from behind, and put into handcuffs as well while resisting being handcuffed.
O'Brien gave the cops a fake name, and when asked for ID gave the cops a fake ID from Alabama. He was then arrested as well.
The rest of the guys were having fun, enjoying the party, and not doing anything terribly wrong. The marijuana issue is scary, because CBJ supposedly ordered everyone to take a drug test, so hopefully nothing comes from that.
The underage drinking will be punished internally, AJ and O'Brien are looking at a 1-2 game suspension.
Theres rumors that AJ said if he was going to be suspended, he will enter the suplimental draft, and forgo this season, so it will be interesting to see how CBJ handles it. He would be a big loss, but at the same time, if he's giving the coach ultimatums I hope Coach doesn't back down.
