Question: Comment: Moving people away from rising ocean levels is a short term fix as the rising carbon levels will eventually make it impossible to breathe once the oceans are acidified killing off millions of species as well as algae which produces oxygen.  If we do not starve we will choke to death.

Answer: Non-insult


Question: Comment: Armed insurrection tends to get one killed. Riel betrayed his people the way Hitler betrayed the Germans, he led them into an unwinnable conflict. Stop romanticizing the past and worshiping your ethnicity.

Answer: Non-insult


Question: Comment: "Homicide refers to the act of killing another human being."  Wikipedia  
With all due respect Foster, apparently you did not read the article closely enough.  While you say the law "doesn't allow" for him to roam the streets while possessing firearms, that is exactly what he did, and only after getting caught was he convicted and sentenced.  
Also, I understand that there are many degrees and culpability of a homicide conviction, however a person with so many prior felonies, again, should not be allowed to roam the streets (with handguns) which, again, is exactly what he did.  
This is all semantics, point being is that this individual should never have had the CHANCE to roam the streets (with handguns) after so many felony convictions.

Answer:
Non-insult
