I actually work in LE and video from domestic and commercial security cameras are always a major piece of information that we look for in every single investigation. So... Yes, LE gives a shit in many countries.

However, also in many countries, like my own, police is very under staffed and burglaries are often on the bottom of the priorities list. Armed robberies, murders, shootings, stabbings, explosions, fires, domestic abuse, rape, to name a few, are the ones that get the highest priority. And those things take a lot of work to find suspects, prove what they're suspected of, write it down and get them convicted.

A case, unfortunately, isn't finished when you catch a suspect. It's a crap load of work to get someone convicted and that gets massively underestimated by people who only read statistics and conclude that LE doesn't care... Most of us do, which is why we join the field.
