You linked to an interesting website.
I perceive that society has become more violent since Biden took office, but a perception is not necessarily reality.
The data at that website confirms my perception.
Deaths from gun violence increased in 2020 (the first year of the pandemic) but increased even more in 2021 and 2022, the Biden years.
Let’s see—Biden refuses to enforce border security, allowing any number of criminal elements/cartels to enter the US. Biden represents the “Defund the Police” movement. Biden represents those who would avoid prosecuting criminals at all if they could get away with it. And Biden policies have damaged the economy, leading to more desperate people who might see crime as their only alternative.
Remember "gun violence" is an Orwellian propaganda term.
Most "gun violence deaths" are suicides, which gun control does not affect.
"Gun violence" Lumps all fatalities which involve firearms into a catchall Orwellian phrase of "gun violence". It creates the impression the solution is to reduce the number of guns, not the number of homicides, suicides or accidents.
Violent crime was on the decline for 24yrs or something before the Soros DAs and defund the police.
At the same time, we had record gun and ammo sales yearly.
Ultimately, only an idiot advocates for gun control in a nation experiencing historic lawlessness.
