Question for WordPress Users

If I want to use a video in a WordPress post, it plays on a propietary WordPress video player, right? Or does it require me to upload to YouTube or some bullshit? I have some undercover videos of corruption here in Colombia (what else is new) regarding the extremely common sale of every kind of prescription drug in the world, walk up, no prescription required, not even a bribe. Just a friendly relationship with the pharmacists. Also, would WordPress have any rules regarding this harder hitting content, if they do have their own video player? Living in a world where I can have 100 oxycontins and 300 Xanax delivered to my door any time of day, as a person with addiction in his genes, has, as you can imagine, caused a little bit of an issue for over a year now. Understatement of the century. Here we get started with the true confessions. Not sure I want to start doing this, at least here. Going to think about it. Serious ramifications once I start down that road.
