KKFI is an open-access station with discrete shows whose hosts are volunteers. It's very unlikely that it will take any kind of stand, though the general tenor of the station is probably liberal.
Advocacy of gun control in Missouri isn't going to get very far. Stick-in-the-mud Republicans run state government, and the governor is not well-respected (one sobriquet I've heard is, "Governor Hee-Haw"). In fact, they have been trying to curtail Kansas City's control of its own police department.
It's all very upsetting to me as a former Kansas Citian. This should have been a happy occasion for those who enjoy such things, but it turned tragic. Everyone with any sense knows what should be done to reduce the likelihood of gun violence, but instead all we get are "thoughts and prayers" which are utterly worthless without action. "Thoughts and prayers" are a cop-out, an excuse for inaction.
It's also probably not widely realized that, 30 years ago, Union Station was abandoned, empty, with a leaky roof that was about to fall apart. I remember paying admission to go into the building the weekend after the city finally got control of it. Even in its diminished state, you could tell that it had really beenMi something, and could be something again. It took a lot of effort and creativity to bring it back to the civic space that it is today. I would hate to see all of that lost because our government officials are too afraid of gun nuts to implement effective measures to prevent senseless violence.
