What issue has arised on definition of Terrorism Act 2000?

basically, the definition of terrorism was "broadened," so now many other crimes that used to be just that--crimes--are now deemed terrorism. Thus, they carry along stronger punishment. The main problem with this, specially after the PATRIOT Act, is that many "regular" activities such as freedom of association could be deemed "terrorist" by these new broad definitions. Although tehre are more 4th amendment *privacy) issues with this new law, even 5th amendment (due process) issues. But I guess it is all mostly due to the PATRIOT Act.
