Drones are a luxury. A steady hand with experience guarantees that such “protection” you speak of is a fantasy in the minds of those who believe they are “invincible”.
Not for long.
I was looking at Los Angeles real estate on the Web yesterday.
One realtor hired a group of build-them-yourself drone hobbyists to take high def aerial videos of various properties and neighborhoods.
Awesome pictures, and equally awesome smoothness and control.
You could stick 5 pounds of explosive on one of those home built drones and fly it right by someone sitting on his 20th floor balcony a couple miles away.
Only a question of time before this becomes a weapon for assassins and terrorists.
