From what I'm seeing online, it looks like Houston started installing Flock cameras in 2022. How were they investigating kidnapping cases before that?

I'd be astonished if decades of methodology and infrastructure for investigating crime have all completely evaporated in the wake of a new and experimental tool -- one that's neither fully demonstrated its reliability as an investigation tool nor that it does not itself create a threat to public safety.

It's a bit polemical to blame their failure to apprehend their suspect on the lack of an tool that shouldn't have been necessary to apprehend the suspect in the first place, don't you think?
