Police don't rank a robbery as very high on there priority list, that's why it's going to take months for the prints to come back, and the security footage is taking so long because the TAB hasn't given the footage to them yet.
A home invasion is a serious offense, especially if someone is attacked during a home invasion, that's why they got the prints done so quick. If your neighbour was just robbed, then there would be little chance the police would spend much time on the case. I have lost count of the number of times I have been robbed, and not once have they ever caught the people that robbed me.
