See thats where the US (and the west really) and all of its Freedoms backfire on them. I find it strange how the president is unwilling to enforce a nationwide quarantine mandate. It makes him (and us, as a matter of fact) look weak IMOChina is also ghetto with it.
They have been snatching people off the streets (like physically), arresting those without masks and who were refusing to take one, or go home, yelling at people on loudspeakers who were not at least 6-10 feet apart, and really not letting people decide...they were enforcing it extremely strictly. They have cameras everywhere including facial recognition and patrollers strolling all day. I think that helped. Kinda like from those apocalyptic disaster movies...but they were not playing games.
In the US, people are still not taking it seriously at all.
