I wouldn't call it terrorism per se, an individual was targeted, not an entire group.  If someone were to attack city hall, or set off an explosive device inside a business, or completly destroy something I may be willing to label it terrorism, but a few broken windows and some spray paint is an assault.  

The American Heritage® Dictionary of the English Language, Fourth Edition has the following definition of terrorism:

ter·ror·ism
n. The unlawful use or threatened use of force or violence by a person or an organized group against people or property with the intention of intimidating or coercing societies or governments, often for ideological or political reasons.

"The best defense against terrorism is a strong offensive against terrorists. That work continues.”

President George W. Bush

"Stuff happens."

Donald Rumsfeld on the rioting after the fall of Baghdad

Terrorism, or whatever you wish to call these acts, it doesn't matter to me.

I wouldn't ask for rehabilitation. My thinking is that the best course of action would be a really long prison sentence. Why? Because I would hate to see them "reformed" like so many in our prison system claim to be, and then reoffend. Given the motivation behind the crimes I would not want them to fake reform and simply become a mentor for the next generation of...whatever we are calling these people.
