On Friday, July 30, 2010, the silent alarm rings from the local bank that is located at 1234 E. 42nd Street. The 911 center also receives calls that that bank doors are locked and shots have been fired. All available patrol units, SWAT, and special forces head to the scene. Upon arrival, your units realize that this was an active bank robbery in progress. After a short period of time, shots ring out. You know that one of the suspects is dead, two officers are wounded, and one is killed. After 4 hours, the gunmen surrender. Now that the scene has settled down, you realize that there are five robbery suspects. Four are in the county jail, and one was shot and killed in the crossfire. Now that the four have been booked, you know this case needs to be transferred to the federal government.

Why would this case be transferred into the federal system?
