IN: Dealing with Police Imposters

[ELB]

By happenstance, all in Indiana:

Case #1:

Young woman driving at 0230, pulled over by car with red light. "Cop" walks up and punches her through open window. Struggle ensues, woman pulls knife, "cop" flees. Real police searching.

Turned out better for her than this gal (Case #1a): http://www.wndu.com/home/headlines/88996057.html" onclick="window.open(this.href);return false;



Case #2:
http://www.nwitimes.com/news/local/lake ... b4adb.html" onclick="window.open(this.href);return false;

Young guy gets pulled over by "cop" and told to hand over wallet. Gets suspicious, pulls own gun and fires at "cop." "Cop" flees. Real police looking for him.
Article does not mention whether he got his wallet back or exactly the legal basis for shooting at the imposter. During the commission of a robbery?

Frankly, I don't really mind him shooting at a police imposter, but that could give him some trouble if the imposter didn't actually threaten to do some serious harm.

Interesting thought: By "merely" claiming to be a police officer, are you effectively making a threat of deadly force or serious injury, regardless of whether a weapon is visible or not?

Further notes: Indiana seems to have a law that a cop making a traffic stop must either be in full uniform or in a fully marked police car. An officer not in uniform is not supposed to make traffic stops in an unmarked police car. Does Texas have a similar law?
