The guy who was shot by federal agents was bipolar and had not been taking his medication. His erratic behavior led to tragedy. Had the agents listened to the man's wife, they might have handled the situation differently and he might still be alive.

From the article on CNN, regarding bipolar disorder:

Symptoms for the manic-depressive illness, during its manic stage, can include increased energy, activity and restlessness; extreme irritability; poor judgment; and provocative, intrusive, or aggressive behavior, according to the National Institute of Mental Health.

There are often periods of normal behavior between the manic and depressive stages, and the disorder can be stabilized with medication, the NIMH said.
