These organizations have enormous budgets and they can't solve simple, non-violent crimes. Why do they need more funding and resources? Is all of that double OT going to finally stop those "brazen" CVS pickpockets?
American police are hot, smelly garbage.
Most other countries have much more intelligent and professional police forces.
What you've described isn't an innate factor of law enforcement. It's a factor of shit quality, cut price, American law enforcement (the biggest factor is the absurd fragmentation of local police departments).
I mean I could tell you who did a robbery, but proving it to the criminal standard of proof is a very different proposition.
Burglary isn't getting solved without a) CCTV and a subsequent ID or b) DNA or fingerprints.
I work on a busy (and I mean busy) robbery squad. An 11% detection rate puts us head and shoulders above the rest of the organisation.
I suggest you go for a police ride-along or listen to dispatch to learn what it's really like. And police are still at the mercy of the laws and courts which can make their efforts ineffective. You can catch all the criminals you want but it won't do anything if they're let out immediately with no consequences.
