They didn't exactly react quickly when it happened, didn't even notice the guy getting up with his shoe in his hand, nor tried to get the pres out of there asap.how do you propose the secret service prevent someone at a press gathering from taking their shoe off and throwing it short of making everyone go barefoot?
But either way, you can look up a long list of failed and successful assassination attempt, the secret service isn't some invincible organization, they screw up all the time, them screwed up this time isn't that spectacular, nor a sign of a conspiracy.
Also, the ban porn thing. The point isn't whether or not they'll be successful at banning porn (it would probably just end up the same as prohibition), the point is that, yes the 2025 people are nuts and would really like to remove plenty of rights from the American public, and plenty of them are in important position and they've infested large swathes of the judiciary. And those people are using Trump as their figurehead/battering ram. I understand that republican voter are adverse to learning things, but it would be nice if they actually took the time to understand what they were voting for.
