While I think your first paragraph is substantially accurate, I do take some issue with the second.80-100 murders in a city of nearly 3 million isn't a problem. When you factor out the gangsta-on-gangsta killings and statistical aberrations like the 10 killed in the van attack; to the regular, law-abiding Torontonian, this city does not have a murder problem. If you're not involved in gangs, drugs or violent crime, your only remotely likely risk of being murdered is through domestic violence (by your spouse, partner, parent, etc).
And, provided no bystanders are killed, do we really care if the gangstas kill each other? And as for the police, their job is not crime prevention, it's enforcement. It's the justice system, not the police that is failing Torontonians, by releasing the violent gang members after each arrest. How can witnesses safely give testimony to police when they know the perp. will be out shortly looking for revenge? Anyone convicted of a gun crime should do hard time and anyone not born here (like me, arrived at age 5) should have their citizenship or landed status revoked and be deported.
First off, yes I do care if gang members try to kill each other, if for no other reason that the attempts invariably do endanger innocent by-standers in a large number of cases.
Beyond that, even complete jackasses and criminals are somebody's kid, often somebody's parent, sibling and lover. That in no way excuses their behavior, nor reduces the need for arrest, and incarceration in these cases.
It does, however, mean that one shouldn't trivialize the value of their lives; that after all is the very sin of which they themselves are guilty.
It also lacks the virtue of nuance, and recognizing that not all are gang members identical, and their circumstances will vary.
Finally, this notion of citizenship revocation really has to go. Citizenship is not something to be granted frivolously, and stripping someone of it should never be automatic or easy.
It fails, among other things, to account for the fact said party may no longer be a citizen of their country of origin, and said country may have no legal obligation to repatriate them.
Let's keep things reasonable in substance and tone.
