DUTIES OF LAW ENFORCEMENT OFFICERS A State Trooper, Deputy Sheriff, or Police Officer may be required to perform many duties including directing traffic, assisting stranded motorists, stopping violators for routine and non-routine violations, responding to alarms, chasing suspects on foot, investigating traffic accidents, investigating industrial and home accidents, making felony and misdemeanor arrests, responding to vicious animal calls and complaints, checking buildings for break-ins, interviewing suspects and victims, testifying in court, executing search and arrest warrants, and more. Most State Police agencies spend more time investigating traffic accidents and enforcing traffic laws, while police departments spend more time investigating non-traffic related criminal activity and other calls for assistance. Police departments do investigate their share of traffic accidents, however. They are usually responsible for accidents occurring within their jurisdiction. State police agencies may take on more traditional police duties also, depending upon their agency, location, etc. TABLE of FREQUENCIES FEDERAL BUREAU OF INVESTIGATION 163.8375/167.600 167.2375 167.4875 167.5625 DRUG ENFORCEMENT AGENCY 418.625/416.050 418.900/416.325 418.750 418.675 418.825/415.600 418.950/416.200 418.975/417.025 418.975 U.S. CUSTOMS SERVICE 165.2375/166.4375 165.2375 166.4625 165.7375 166.4625/166.5875 162.825 U.S. SECRET SERVICE 32.23 Able 166.5125 Alpha 165.7875 Baker 165.375 Charlie 169.925 Delta 407.850 Echo 415.700 Fox 166.400 Golf 166.2125 Hotel 407.925 India 170.000 Juliet 167.825 Kilo 168.7875 Lima 165.2125 Mike 167.025 November 166.400 Papa 164.8875 Oscar 166.700 Quebec 166.400 Romeo 166.5125 Sierra 164.650 Tango 361.6 Uniform 164.100 Victor 167.025 Whiskey 166.4625 Xray 162.6875 Yankee 171.2875 Zulu 415.675 Black 414.850 Brown 414.950 Orange 414.975 Red 414.650 Silver 415.875 Violet 414.675 Yellow 46.75 46.70 46.80 165.850 INTERNAL REVENUE SERVICE 165.950/167.000 167.000 165.950 166.000/167.100 166.000 165.4625/166.5875 166.4625 418.225/414.7 418.225 418.175
