Hello, I am wondering how big a problem home invasions are in the SF bay area, particularly Oakland? This is in regards to a small scale grow operation with less than 100 plants and only the two people growing having knowlede of the location. I have a friend who's son told his friends about her setup and the sons friends raided the home at gunpoint and stole everything. She ended up in the hospital. What security measures can one take to avoid this? This took place in Seattle FYI...
