Understand that anything CA Court says about Foothill Ranch is purely used as an insult to SoCal and is not based on anything factual other than his hate for her.
If you look at that site someone posted - and look a bit deeper - it states, "Burglary Alarm Audible" for burglaries
There was also a "Shooting" according to that website. Which basically was "shots heard" or "there were some kids playing with fireworks and I got scared so I called the police"
Just look deeper into things before making a judgement.
Look at the police blotter - Look at Lake Forest - (as Foothill Ranch section won't populate) Then you have to familiarize yourself with the names of Foothill Ranch streets to weed out the bad areas of Lake Forest that will demand attention in that blotter.

Lake Forest police don't care to come to Foothill Ranch? Where is that information coming from?
Just because an enclave within a large city has a population of 10,000 doesn't mean that there will be no crime. Any time you have access to an area, a traveler with no ethical standing may try to come up quick.
