Lawmakers get involved in issues of safety and life and death.
The American Congress is currently spending time investigating whether Major League Baseball is doing enough to stop illegal performance-enhancing drugs from tainting that game. There is evidence linking steroid usage with some suicides and premature deaths, so that investigation involves matters of life and death.
There was a major outcry about America's infrastructure after a major bridge collapse in Minnesota on 8/1/2007. Lawmakers became involved, because it was a matter of life and death for American people. I take a bridge over the Mississippi River twice a day, on my way to and from a job that contributes to the American economy. I should feel safe going over that bridge.
What about the use of Tasers? Obviously, this is becoming a matter of life and death too. Too many people are dying when Tasers are being used. Yes the police need to be able to protect the public, and this includes subduing unruly suspects. But a line must be drawn somewhere, and I believe lawmakers should investigate whether to outlaw the Taser weapon, or what precise restrictions there should be.
