Comment: Castration is best for him
Threat

Comment: United used to be a decent airline. In October 2010, they merged with Continental which had always, in my experience, been a horrible airline. We were flying back from New England when Continental-uniformed staff stepped into United Airlines jobs and immediately the customer service took a nose-dive. I filed a complaint for the way they treated my mother-in-law for just being a little slow to respond to them. That was the same weekend the TSA started the nude photoscanning and pat down searches, so it was a miserable trip home and we're still waiting to hear back on that complaint.

I wasn't surprised to see this in the news. Arrogance will always show in a company eventually. That their own crew had priority over a passenger makes me wonder if United's CEOs and middle managers need to take a course on capitalism.

Back of this may be a government regulation about flight crew transport. Many business problems trace back to government rules forcing impossible choices.
Non-threat

Comment: Dealing specifically with the MS-13 issue he addressed, the police should not even be involved. This is a group of armed people that illegally entered the country to cause harm, that is war, and it is the jurisdiction of the armed forces. The military should treat it as such, take no prisoners, and head-shot anyone with that stupid MS-13 face tattoo. And no one gets that ink by accident.
