I agree the act was awful but no where in the constitution does it say ‘terrorism’ or prescribe that offense. Congress has (though illegally). MA probably has too. I’d argue the MA law is the one he should be brought to justice under.
I also fear that at some point certain elements of government are more interested in using their power to crush conservatives, Christians and all us other “right wing extremists” they keep chattering about.
However, and this is a big however, we are at war with Islamic Radicals that want to kill us. It doesn't matter if you, the government or anyone else doesn't acknowledge that, it is a fact and has been for some time. It doesn't matter that many refuse to accept that and as such will allow those enemies to roll over us, but I refuse to stick my head in the sand and ignore the threat. They declared war on us whether we like it or not.
