While it's tempting to assume the RCMP are doing nothing about this, that isn't true. About a week ago I was at the Diamond Head parking lot when someone rolled in and parked to talk to me. It was an RCMP patrol.
The officer described a scenario that had never occurred to me. The people breaking into cars at trailheads can stay there for some time, pretending to be preparing to leave to go hiking/whatever, or preparing to go home. They just look busy, tying boots etc. while there are people in the parking lot, then do their deeds when there's no one left in the lot.
So if you notice this pattern of behavior, please get their license plate number. If you're wrong about the party, nothing will come of it. But if it's a number the RCMP are tracking, it may be the needed break.
While we were talking, a couple running on tiny snowshoes entered the conversation. It turned out they had left wallets, cellphones etc. in their car. Just too heavy to carry for a critically timed run, I suppose. As I've said repeatedly, would people please stop leaving such things in their cars. Not only does it encourage the thieves to keep breaking into cars containing valuables, but it encourages them to break into mine even though they won't find anything.
The slashed tires suggests there is more to this than kleptomaniacs or people desperate to generate cash. There may be an element of anger/resentment about a whole complex of stuff such as environmentalism, city elites keeping the locals from motorized use of Garibaldi Park etc.
What can you do?
1. Don't leave valuables in your car.
2. Install a car alarm that has a loud horn
3. Have comprehensive insurance on your car so that ICBC is impacted and gains an interest in this problem.
4. Buy a cheap fabric long rifle case and leave it draped in plain sight, or a hard case and leave it open in the car.
