Gundato: And abducting tourists and killing them is kidnapping and murder.
Blowing up buildings is probably another specific crime.
Not sure what the specific law is, but I am sure there is a specific crime that corresponds to hacking.
But, if the intent is to coerce people through fear and intimidation (to terrorize :p), it is terrorism.
Siannah: According to your definition:
any crime commited with a gun or knife = terrorism
a punk shoving a granny away = terrorism
yaywalking, forcing a car to stop = terrorism
You basically just admited to have no clue about the actual laws being in force, you're just supporting a specific dictonary-definition.
I did? Wow, thanks for informing me.
Once again, from dictionary.com
http://dictionary.reference.com/browse/terrorism More importantly
"the use of violence and threats to intimidate or coerce, esp. for political purposes"
As for violence
"swift and intense force"
"an unjust or unwarranted exertion of force or power, as against rights or laws"
So of your three examples:
any crime involving a gun or knife: Quite probably counts as terrorism. Use of a weapon (threat) to intimidate and/or coerce. I would posit requiring the "for political purposes" angle, if you want a less specific one.
"a punk shoving a granny away": If they are trying to intimidate or coerce her into doing something, probably. But if it is just senseless violence (which is more what you depicted), then not really. Just plain violence.
"jaywalking/forcing a car to stop": That one is a pretty grey area. If you count "If you run me over, your car will get dented" as intimidation or coercion, maybe. But again, I would posit requiring the "for political purposes"
But, so that LordCinnamon won't get angry, I would have to say that you are making ridiculous comparisons to go off topic. For shame :p
For those playing at home:
Hacking/DDOS'ing the servers counts as a "swift and intense force". It was CLEARLY done to intimidate and coerce. And it was political as hell. So I guess dictionary.com mus be wrong :p
