SSS is more difficult these days...
When the shitbag disappears and his cell signal (even dirtbags carry smartphones) is on your property... where do they start looking? And when your cell signal is right nearby? Who do you think they start prosecuting?
People need to start thinking in terms of "every moment of your life and movement" is trackable. Your car is broadcasting your location every moment if it was made after 2014. Whether you have GPS map option or not. Your Cell Phone is triangulatable down to yards. Every WiFi you walk past... knows you were there. Cameras are everywhere... maybe not in the middle of a field... but on the road getting to the field or woods. And in cities, assume that every square inch is under some kind of surveillance all the time.
Modern problems require modern solutions... Faraday bags for phones when not actually being used. Burner phones with cards bought from Bodegas... Older "beater" cars that do not GPS track... A few 'spare' license plates that come from cars that look similar to yours... (beware of these in a municipality with plate readers on cruisers.) Keep your EZ Pass in a faraday bag unless on a toll road... and remember that now those "Toll Stations" are overhead cameras taking your picture and getting your license plate while collecting your toll. Or getting your plate to send you a toll bill or a ticket. Avoid Toll Roads.
Most major parking lots have cameras in them. In car dash cams are everywhere and sending stuff to the cloud. Every street has Ring Cameras and many are recording all the time. I can tell you that even here in Mayberry, if we want to, we can follow a car 'almost' anywhere with enough effort. From an office. Or at least could 5 years ago. I am sure it's better now.
So if one is going to contemplate defending one's self, the Shovel and STFU part is not going to be an entire answer.
I'm surprised we have never started a thread here on "Avoiding Surveillance" and the related tradecraft. Then again, such a thread can be used for evil, too. So not necessarily advocating it. And following 'those' guidelines will show up like a red flag. Phones that "appear and disappear" as they go into Faraday bags are a pattern that gets noticed fast.
These days, assume everything you do, everywhere you go... everywhere your car goes... is recorded somewhere.
If folks have not seen the movie "Enemy of the State" with Gene Hackman from the 1990's, that was tech from 30 years ago. And it was a bit 'ahead of its time.' A bit. What is out there now is far more pervasive and powerful. Movie is worth watching. Twice.
Anyhoo... best advice is know the rules, know what constitutes self defense in your area. Know how to act after a shoot. And practice avoiding getting into a potential bad situation. The best shoot is the one avoided.
And learn all about surveillance, counter-surveillance and surveillance avoidance. If our intelligence, LE and National Technical Means keeps getting weaponized against people at the current rate, these will become basic survival skills in a dictatorial communist police state.
