DEA
Every drug trade that you engage in has a 1% chance of being interrupted by the DEA. The result of such an event is that the cash and the drugs involved in the transaction are impounded by a non-player-controlled entity called the DEA Field Office. This entity shows up in the player list and can be found by using the search player facility. It is a completely automated character, which does absolutely nothing except sit on the cash and drugs that are impounded. The DEA Field Office has an insanely high number of defensive soldiers with a randomized morale, that can exceed what any player can currently attain. It can be raided and stolen from like any regular player character, but you won't get a fair chance unless you work in a team to bring it down.
Every three hours, a portion of the cash and drugs that remain on the DEA Field Office is moved to another non-player character called the DEA HQ. This is an even bigger fortress, with more defensive soldiers. Obviously, if the DEA Field Office isn't razed to the ground regularly, the DEA HQ will quickly fill up with very high quantities of cash and drugs.

# DEA Field Office
The DEA HQ has ten times the average number of soldiers that the highest ranking players have, while the DEA Field Office has four times that average. Because you need at least one-fifith the number of soldiers of an opponent to be able to steal from him, neither of the DEA's can be stolen from without raiding them first. It is impossible to take down the DEA HQ to a level that will allow you to steal from him on your own. It is possible to do for the DEA Field Office, although you'll never get a fair chance if you do so without help from other players. Stealing from the DEA's is all about dedicated team effort or blind luck.
Both the DEA Field Office and the DEA HQ regain some of their defensive soldiers every 90 minutes roughly. The morale of these soldiers is determined daily, with the maintenance phase.
The corrupt lawyer class is exempt from DEA busts. Although this is still to be confirmed due to the removal of the lawyer class at one point and being put back. Though they ARE immune from dirty cops arrests.
