They could easily find it for most people. It is generally public record, in my county it's available online, unless the individual built the home themselves (mine isn't on file because I opted out of building codes and planning, but commercial home builders can't do that here).

But let's be real, police constantly barge in to the wrong address, looking for people that have been gone for years, accomplishing not much more than shooting a beloved dog on a hair-brained last second witch hunt. It's not that they can't do it, it's that they have the attention span and executive planning facilities of a burnt out coke addict 3 hours post their latest scratch off ticket winnings.
