Absolutely not all cops and prosecutors, or even the majority of them, are this lazy. Every tool is a tool that lets them "be event lazier" and make it "easier for them to abuse us". Removing any tool that let bad-actors be lazy is not an alternative for removing the bad-actor themselves.
This situation the equivalent of an eye-witness saying "Ya, I think it might have been this person I know, Tom!" and a cop/prosecutor taking that at face value and arresting Tom (and the system that allowed that to happen).
The people who make decisions and take action so (grossly) negligently need to be held accountable and face consequences. Blaming the tool (whatever tool it is) is giving the people who have the actual responsibility an escape hatch to avoid accountability.
