Try! as opposed to giving up the first chance they get.
Brand you are obviously anti police, that stands out a mile and so any sensible conversation with you about them is going to be impossible.
Tracking in this sense means the Company responsible for monitoring the trackers. This obviously isnt the police. Their job is to try and find the vans. That can take time, unless you have a magic wand which finds things immediately.
I am sure they are trying but this wasn't just an opportune theft to steal 2 vans full of expensive bikes and somehow disable the trackers. But without even knowing what they are doing you are on their back straight away.
I am sure you have all the answers even though you dont have a clue what the questions were to begin with.
