Scams & alerts....
I saw a "unmarked" unit doing a traffic stop in a business district about 3 streets up from my apt complex.
It was a urban street but
I would have pulled into a well lit parking lot or 24hr market, contacted the LE non emergency # or 911 dispatch & advise them of the officer or deputy's description.
If the cop or "drug agent" was legit, Id request the area supervisor, watch commander or police patrol supervisor.
Id document the time/location/description of the officer(s)/etc. This would include the LE officer's vehicle & tag #.
My city's PD uses a IA(internal affairs) form that requests the vehicle description & tag # in any statement.
Fake cops & "plain-clothes" officers who later got IA complaints or OPS(professional standards) beefs are not uncommon in my metro area.
About 3 years ago, a "US Dept of Homeland Security special agent" nearly ran a mom off the road as she let her kids off at school. The local sheriff's office told the media the subject was a
real undercover agent & was working in that area when the incident took place.
I'd add that street people & homeless in my city now like to stroll up & down the lanes.
Keep an eye on them too. Not just for safety but they can quickly reach in & snag your bag, case, purse, etc. Then bolt off.
People hiding or jumping out at gas pumps is a common tactic too. Be alert when you pump gas. If time permits, circle the lot or stations
first. Be aware of your vehicle & use the mirrors/windows.
Crooks & robbers want victims on cell phones or distracted so they can lay them out or catch them off guard.
