Frankly, when you twin the language of assassination threats with Donald Trump's suggestion that a Hillary Clinton electoral victory would be illegitimate, it scares the hell out of me.

There are all sorts of shades of gray when you're working on economic policy and tax policy and health care policy. There's no gray on this issue, to me. This is a gun lobby that is raging out of control, that doesn't even represent its own members.

The anti-gun-violence movement was essentially asleep from 1994 to 2012, and during that time, the gun lobby built up enormous political power.

If we have a president who asked for a mandate on combating gun violence, as Hillary Clinton is requesting, that's going to be really impactful. I will certainly defer to her when it comes to the exact pace and content of legislative action, but I expect it will be at the top of her agenda. It will certainly be at the top of mine.

One of the myths about the Internet of Things is that companies have all the data they need, but their real challenge is making sense of it. In reality, the cost of collecting some kinds of data remains too high, the quality of the data isn't always good enough, and it remains difficult to integrate multiple data sources.

There's no more personal issue than gun violence; every one of these stories is a life lost, i'm hoping that over the long term, as I tell these stories, that it will help to open people's eyes.

Donald Trump has a lot of supporters with a deep hatred of Hillary Clinton and access to incredibly powerful lethal weapons.
