The heck is wrong with folks these days?

 

[Ontario Mom]

Trump deserves our hatred, but no one is calling for him to be assassinated. Come on

I don't hate the guy but thankfully on here at least, no one is calling for his death.
Elsewhere in society, it happens every day. It's flipping insane.

 

[Sundog]

Trump deserves our hatred, but no one is calling for him to be assassinated. Come on

I don't hate our President, but there have been quite a few assassination attempts by some of the most deranged haters. Sad to see. And tragic, of course, for the country. But this guy, at least, will be held accountable in federal court.

 

[vls12345]

Wow. Didn't expect this to be the direction the case went! Unbelievable.

It does feel like there are so many unhinged, violent people out there these days.

 

[airportwoman]

The names have me thinking that he and his mother were born in Russia. Does anyone know if this is true, and if so, when did they emigrate?

Nikita Casap, 17, was arrested in March and charged with two counts of first-degree murder and two counts of hiding a corpse after killing his mother, Tatiana Casap, 35, and stepfather, Donald Mayer, 51, in their Waukesha home — then stashing their bullet-riddled bodies under blankets for weeks.

Just pure evil & pure evil influences.

This almost sounds like a 2025 version of "Helter Skelter" - commit crimes and make the authorities think someone else did it.
