Agents almost never get recognized for their acts of valor. For one thing, a successful operation puts agents at risk. Often, agent identities must be kept secret to protect them and their families from disgruntled criminals who want revenge. For instance, Jay Dobyns achieved international acclaim for infiltrating the Hells Angels. The Hells Angels is a motorcycle club often under fire from law enforcement agents for selling firearms and drugs. His investigation resulted in the indictment of several members of the organization for racketeering.
During the court proceedings, Dobyns' identity was revealed. The Hells Angels, the Mara Salvatrucha gang, and the Aryan Brotherhood threatened to kill Dobyns. Four years after the court hearings, Dobyns' home was burnt down. General consensus is that it wasn't because he left the stove on.
In other words, you don't want to be a famous ATF agent. This isn't the type of career that offers tickets to exclusive parties and free limo rides. You'll never be an agent who needs his own agent.
