I agree in principle with the point that there is a lawful basis for probable cause and arrest warrants. Where I disagree is on whether an individual has the right to resist if said factors are being acted upon unlawfully. Police are not the judge and jury, but they also should not be exempt from entrapment laws, which sadly they are at the federal level. Similarly, while prosecutors are afforded a certain degree of latitude in order to try criminals, they should not be exempt from perjury laws, which presently they are.
Both law enforcement and prosecutors are capable of becoming tyrants if they are given too much power, and the flagrant abuse of law that has been observed of late should clue people in on the fact that America has some real problems in this department.
