The motorcyclist OUGHT to face the traffic charges - that was never a topic for serious debate.
But the actions of the LEO (brandishing a gun without making any attempt to identify himself) ought not go unpunished, even if it's only a formal letter of reprimand and a couple of weeks of mandatory anger management/use of force classes - to be completed on his own time, of course.
The invasion of the cyclist's home, seizure of his property, and bringing of the bogus charges ought to bring their own consequences against local LEOs, DA, and the (seemingly anonymous) judge who signed the warrant. My suggestion is that they ought to pay - personally - all court costs and lawyer's fees to defend against the bogus charges, as well as anything else connected with loss of income and such.
Fat chance.
