Well, assuming basic accuracy of the OP as to the LEOs words, if the LEO was looking for help he sure approached it badly.
"I just wanted to ask you some questions about what your doing and were you have been."
is far different than
"I was hoping maybe you could help us."
Heck, after mulling it over, the LEO could have been trying to get info for a news article for an inhouse paper or some other innocuous or even supportive reason. If that was the case, it is unfortunate that the LEO used "standard" LEO language to start with.
Even it wasn't an LEO and was instead pretty much any other person in the world, including my fiancee, approaching me with "I just wanted to ask you some questions about what your doing and were you have been." it would result in an immediately defensive response from me (and from many, many people) of none of your business - go annoy someone else (I could explain why psychologically such an approach makes many people defensive and why, even knowing that, LEO are even trained to use similar language but it would be rather long and probably boring for most people and I don't feel like typing that much
).
