What's wrong with your maths?
I could ask the same question of you—because from my perspective, the only difference between victims being injured or killed is a matter of luck. I consider it an error of the highest order to include that sort of randomness in the factors which drive public policy.
A person with issues made what might have been a final plea for help the night before and everyone just blew it off.
"Online" is such a vague description. Was this somewhere like Facebook or G+, where tying your activity to your offline location is simple, or was it on 4chan or Xbox Live where the "identity protections" in place may have prevented properly contacting the police department in the correct local area?
...do you think someone can commit mass murder on this scale with knives and baseball bats?
It does not matter what I think, I happen to know it has happened. While typically these events are "less fatal" I don't think a 0-deaths attack should be considered better if victim counts remain high. Personally, I wonder why you prioritize guns, when nearly every previous mass shooting perpetrator has shown poor mental health? (It's still a little early in the reporting cycle for a solid analysis in this latest attack.) Since this is such a universal factor, even past the availability of firearms, I would say improving our treatment of mental health issues should take a higher priority in responding to mass attacks.
I caution attempts at social engineering result in greater injustices than those they seek to fight against.
I would say that the first thing those attempting social engineering should seek is to utilize the solutions they propose. For instance, it's amazing how many of the politicians in the US who seek to raise the minimum wage also make broad use of unpaid interns. If even the crusaders can't manage to pay everybody minimum wage (not the new level of $10, $15, or whatever is being proposed today, but just the current amount), what makes you so certain it's a great idea?
I'm not entirely sure you're not trolling, but I'll bite anyway.
The US Constitution states that the purpose of copyright is "to promote the progress of science and useful arts", artists and inventors may be granted a (temporary, limited) exclusive right to their work. Anytime copyright comes up among my group of friends (who include a large number of writers, musicians, and graphical artists, in addition to programmers) copyright is a fairly contentious issue. I tend to like to argue the position that any "common", mass produced work that is unavailable for public purchase for longer than one year has outlived its' salable value and should lose copyright protection. (This is particularly true in the age of digital distribution, where "shelf space" is a non-issue.) Fine art (where only one copy of the item ever gets created) clearly requires a different definition for copyright term, but for the things which usually are referenced in these debates online -- CDs, mass market books, newsclippings, etc. -- a strictly limited term is far more beneficial to keeping works available to the public.
I don't think I dare look at your link right now, but your question has been answered. To quote from that Wikipedia article: "The lead plaintiff was Frank Ricci, who had been a firefighter at the New Haven station for 11 years.
Make whatever noises you like: just because a person is part of the privileged class in the two most visible categories of discrimination (race & gender) doesn't exclude them from being a member of any other legally protected class.
I'm sure you know about Westinghouse and Edison setting up parallel electricity networks in New York, but it was even more extreme for the telegraph. In 1850 there were 75 telegraph companies, ten of which served New York; in 1866 there was only one.
False. Since you specifically mentioned New York, here's an article about how that technology developed. Specifically, it states that "To encourage growth in this new electricity infrastructure, New York, like all of the other states, protected the utilities’ investment by granting them an exclusive right to serve customers." (Emphasis mine.) Believe what you want about the importance of monopoly busting, but the sad truth is that for every common example people give of "natural" monopolies, the government had a hand in why the service in question is a monopoly market.
