As for the first link, although it's absolutely crazy (especially considering that the "less vulnerable" people likely subsidize most of the police force) we do live in a society and someone has to make the decisions. These people are elected or appointed by the elected. If we don't like it we can protest and run another candidate and elect them.
It honestly sounds like pragmatism from a police force that has been decimated by budget cuts made by elected representatives whose electorate simply doesn't want to pay the taxes required to fully fund a police force that can service everyone. You can't have it both ways. If it bothers you then vote for someone who says they will increase the budget by other cutting programs you don't value as much or by raising taxes.
Take action through the democratic process to invoke the change you'd like to see and shape the world. The people passing policy you don't like certainly have and are the authority precisely because they have. But there's nothing stopping you.
