I have pulled the same hidden hand trick when confronting trespassers on some property i took care of .
With all the foreclosed homes the thieves are having a field day.
They claimed they thought the house was abandoned even though the lights were on.
This home was my fathers and after he passed away i was living in the back yard in my motor home while i got it cleaned up and ready for sale.
Four homes in the area had been broken into and stripped in 2 months
They even took the electrical wiring out of the walls in one.
When i confronted the trespassers i was armed with a 1911 but my hidden hand was on a can of bear repellent.
if they had been armed and went for a weapon the bear repellent would have given me the time to pull my weapon while they were blindly trying to see
If your phone has a camera learn how to take a photo with it but while it looks like you are checking a text massage, taking a phone call, or
checking a shopping list.
if you see someone suspicious then you can get a photo just in case.
By the way i am a ex-federal security officer.
Never fight fair.
