I am currently in Israel. I noticed that many homes here have elaborate security systems. I was explained that there are many break-ins, and that the thieves are very ingenious. Especially on holidays when they know people will be away for a specific amount of time they can strike with a reckless abandon on a persons home. Thieves climb terraces and saw through bars on windows assured that nobody is watching them when everyone is in Synagogue or away having a Seder by their parents.
Professionals indeed.
