According to Filenko he was out walking for those 20 minutes and not near his car at all. So he had to have seen the guys after he got out of the patrol and was already walking around for some time.
Which is convenient for not being on dash cam....
I think the description was where I got hung up real quick on this. It was too vague considering he was "suspicious" he never even said what they were doing that was so suspicious either.
Right what was the probable cause for his pursuit and for back-up? JMO
