Laws are just a consequence of an actual cultural change, and can only succeed (and not precede) the conversion of hearts and minds. Voting and democracy should not become a device to placate the dissatisfied masses into silence, make them lineup for ballot, to choose a lesser evil who, in most likelihood, will turn out to be a egotistical power-seeker. We shouldn't conflate voting with "will of the people."
What else should you expect when people are limited to only two political parties? It could be worse with only one political party.
We don't need more political parties, we need solutions to manage the incompatibility.
But you end up in a situation of further tragedy where people start destroying property and assaulting others, and they screwed up by doing so. The message has been diluted, lost in all the noise. Expanding it nationwide hasn't broadcast the message positively.
It's juvenile and short sighted, the people are on their side, saying yes this was wrong, yes this has to stop, murder is unacceptable, etc. They are now looking at the situation with a different viewpoint, asking themselves if the police violence may be justified with this group, look at what they did to our community when WE AGREED with them and were willing to help.
That isn't a political thought, that is a rational thought. Destroying communities, rioting, looting, killing people, it never brings more people into your corner. America is a civil society that respects law and order. Much of America now is just happy they don't have to live around anywhere where this is happening, that is going to be the only takeaway from this tragedy now. The chorus on social media doesn't reflect that. The riots turned average Americans against this event.
A barrier, metaphorically, was quickly slammed up between people, and now it's just noise and chaos.
