Trump is in charge of the country right now. Some of this obviously falls on him. Don't discount the number of "actors" that support Trump that are out there creating havock.
Democrat polticians could do a better job condemning the looting and rioting; although by and large....they are doing so.
As far as general members of society go:
If you are an American and you are upset with the state of society under Trump....vote him out. Don't just riot and loot....vote.
If you are a Trump supporter who think everything under the Trump regime is great except for the rioting/looting .....take a moment to put yourself in others shoes and ask yourself why is this going on If you are intellectually honest in this exercise....you'll come to a reason that will probably make you uncomfortable.
When you say Trump is in charge, are you also accounting for the facts of how the laws of our country's republic is set up, that it is directly outlined, that the federal military is not allowed to be involved in the domestic states, outside of the Insurrection Act of 1807? Specifically, the president does not have the authority to "be in charge" in this instance unless the local governments requests help. That is why he asks almost EVERY single day at his press conference for the local states to please ask. They won't. He repeatedly says "all you have to do is call. We are ready immediately."
The reality is, if you are upset with the state of society, it's not "under Trump", it's "here in America" and you must look at who is pushing it and who is attempting to stop it.
The president has withheld funding to those states not willing to get help, he's asked almost every day. He's passed legislation that heavily penalizes people who tear down statues or commit violent crime. He has put task force after task force into place to crack down on these people, etc. In Chicago, when the mayor finally let him in, his agents weren't out there busting people on the streets. They were out there executing warrants to remove and process people who were being turned loose or not served. They served over 200 warrants in a couple days.
The Democrats on the other hand only began criticizing or calling for the violence to end once Don Lemon went on CNN and said "Joe Biden needs to speak out on this because the polls are tightening up". Before that, his staffers were asking for donations to help free "peaceful protesters" who were being arrested. Kamala Harris. on June 1, tweeted and asked for donations to help free those arrested in Minneapolis. She went on The Colbert Report and said the violence would not stop before the election, after the election, and shouldn't until they get their "justice".
Several key democratic politicians have outright called for people to keep protesting and none of these politicains have been disavowed, let alone, corrected by their party.
Two weeks ago, there was a 4-day nationally televised Democratic National Convention. The platform was there for the Democrats to spread any message they wanted and not ONE person said ONE word about stopping the violence. There was absolutely nothing said until Lemon mentioned the polls slipping.
It's clear.The democratic party is using chaos and divisiveness to fuel their campaign and it is horribly wrong. We should all be together, yet every day there is something encouraging unrest and protest to wedge things apart further. Look at how Kenosha picked up the phone and asked for help and how quickly it has become a true peaceful protest. Compare that to Portland where we are now on day 97 or so of protest, riot, looting, arson, and now a few murders as the Portland mayor (who is also, by their law, the Chief Of Police), continues to try to say this somehow someones' fault other than the man who is charge o the city.
