If I buy a front door lock that has a systemic manufacturing problem and someone breaks into my house, I might want to sue the manufacturer.

But if someone breaks into my house--regardless of whether it was unlocked, the lock was defective, or they broke a window--and the police are negligent or incompetent in investigating or prosecuting the perpetrators, in what world is that a) not the police's fault? and b) an opportunity for the _police_ to sue the _manufacturer_?

If I start a cultural movement to get rid of front door locks and it gains traction, and then B&Es spike, can the police sue _me_ too?

[plagiarist]

If you make a lock that is recognizable and easily broken to the extent that B&Es double nationwide, I don't see a problem with cities suing you over it.

I don't know why you want to try and link the idea of a cultural movement? There's very clearly a difference between a defective product and a deliberate decision.
