Experts say wealthy individuals are purchasing bulletproof cars, safe rooms, employing armed guards, and even constructing walls with barbed wire around their properties.

The issue of violent crime is nothing new to Los Angeles, but a spillover to upscale neighborhoods has put elites on edge. The Hollywood Reporter reports agencies who provide private security are seeing increasing demand for private patrols. 

Since August, Rising S Company, a company that builds underground bunkers, has installed 13 safe rooms, nine safe doors, two underground bunker shelters, and two window fortifications across Brentwood Park, Beverly Park, and Paradise Cove. This compares with seven safe rooms in California in the last 2.5 years. 

Estate manager Bryan Peele, president and founder of the L.A.-based Estate Managers Coalition, said his clients have "fully equipped safe rooms that they can live in for a few days, if necessary, that are completely hard-wired with phone cables, Internet, everything."

One of Peele's clients has three bulletproof cars and wears fake Rolexes. "This guy will take a $200,000 Rolex and copy it, using stainless steel and other metals, so it looks like the original but costs maybe $2,000-$3,000 per watch. So, in the event that it's stolen, the client is out a lot less money," he said. 

Many upscale homes are installing more cameras, constructing fences with barbed wire, and employing 24-7 security details that will protect them from once their private jet touches down to their mansions. 

Some people are even taking firearm and self-defense classes so they will know how to defend their family and or themselves in an emergency.
