I had no authority to enforce state and local laws. My authority began and ended with limited federal statutes. Titles 8 and 18 to be precise.
I had limited Title 21 (durge enforcement) and Title 19 (customs laws) which was specifically delegated to the INS by DEA and US Customs. Last time I checked there are no federal agents which have general arrest authority to arrest for any violation of federal law much less state laws.
If I stopped someone for speeding there is nothing I could do with them as there is no federal statute I could enforce. We had no federal ticket books.
If I observed a felony while on duty for an offense not covered by my authority all I could do was to temporarily detain the suspect and call the agency with jurisdiction to come and get him.
Thanks.
As it should be.
