Local police have reminded East County residents of a simple pattern behind many home burglaries: unlocked doors and windows, and car keys left in plain sight near entryways. Two easy habits tonight: double-check every door and window, and keep car keys somewhere less visible. Small steps, real peace of mind.

Home safety starts with awareness—and preparedness goes beyond locking the door. Explore Split Second Response courses to build real-world confidence and practical protection skills for yourself and your family. Learn more and register today.

A quick, important update for CCW holders: as of September 1, California requires DOJ fingerprint-based eligibility confirmation before a renewal can be processed. If your permit is coming up for renewal, plan for the extra step and start early—there's a 90-day submission window after expiration.

Questions about timing? We're glad to help.
