That's the thing though you can't "increase your security" against this type of threat.
If someone wants to kill someone else... they're going to do it.
Defend against a short range attack and someone will buy a scope.
Defend against that and someone will crash a drone into your head at 100 MPH.
It's comical to think that the solution to this problem is defending against the threat when the real threat is their own corporate policy that plays with people's lives for profit.
We are witnessing the realignment/restructuring of the exixting order. As such, many other dramatic events will surely follow.
Absolutely. It's all mater of statistics. There are so many CEOs of unpopular/despised companies and there are so many people who hate them with homicidal passion.
All it takes if for one of those CEOs get cavalier of personal security and one of his potential killers apply enough training, intelligence and luck.
Something that happened in Dallas six decades ago with an antiquated Italian bolt action rifle being in hands of person with just enough ex-Marine training.
