what these types of low level thugs do for revenge most of the time from when i heard people messing with hoods and stuff drinking on the street causing problems is they follow you home and break a window at night or something like that. its usually small but annoying.
That would be a very BAD idea.

If they did that, breaking the window would probably activate the MK2 version of this device. The (MK2) drone would activate, and rapidly fly out of the window, and its AI system would follow the crook/bad person home.
It would then following them inside, and wreak horrible revenge, on a similar, but somewhat worse, than the MK1's capabilities.
Apparently, the ex-NASA inventor, has had a future planning meeting, and decided to continue this up to the fourteenth generation.
AKA, the MK14 unit.
Which is not only rumored to have AI so good, that it can even go online and any forums which mention about the MK1, it can participate in the discussions.
Rumor has it that he has already built the MK14 unit, and it is active. So look out for it.
