Proctas Defender

[Dum-Dum]

Home security is more important.
You can put all the theft deterrence you like on your car, the thieves will just break into your house and threaten you with violence if you don't hand over the keys.

That is highly unlikely for a defender!
It's to do with the police putting more effort into investigating serious crimes thus increasing the chance of getting caught.
The fact that an aggravated burglary carries a much more substantial prison sentence compared to a simple theft of a vehicle.
And the fact that to do a decent aggravated burglary you need a minimum of 4 people all of whom need their cut of the profits compared to 1 or 2 just to steal the car on it's own.
