layers of security personnel in the USA

[Marilyn Mason]

After seeing the border patrol guys in the Aderondacks I started running the 
# of security/law enforcement layers there are in the country.
You've got the army. navy, airforce, marines, border patrol, coast guard, 
state police, county sherrifs, village police, city police,FBI, CIA, secret 
service, maybe some other band of spooks.
How many did I miss?
Just curious.
