Seems that that pesky fourth amendment is getting in the way of police. Notice that they don’t even have to knock if the officers feel that quick entry is desireable.
Once again, the slow erosion of our rights continues.
I would hate to be the officer (or officers) that enters my home uninvited, at any time of the day. I would hope that for their safety (and mine) that they choose to knock, and ask to enter.
