If the new Federal Government position is that "Terrorism" is an act of violence by ethnic minorities, statistically, most of the actions of Hawaii residents (including "speech") will increasingly be viewed in a "Terrorist" light.
It's been moving in that direction for a long time.  
McVeigh, Kleibold, Holmes, Roof, Christian (the Portland stabber), whoever set off the bomb in the Minnesota Mosque, and now Fields.
On the last three, the sitting POTUS has carefullly avoided referring to them as "Terrorists".  But, they are.  No question.
There are TERRORISTS roaming America.  That is certain.
Perhaps this incident will serve, eventually, to highlight the need to overcome American racism in order to fully address the terroristic proclivities that occur in HUMANS.  Not just certain races.  That is essential for America's National Security.
BUT, immediately, America should consider whether the term "TERRORIST" has become co-opted as a code word for racists.
The evidence suggest it has.
