What part "...shall not be violated..." in the 4th amendment is difficult to understand?

No warrants needed, so forget the last half of the amendment; that's already been tossed into the growing heap of discarded individual rights.

What constitutes 'unreasonable search and seizure"?
Right now, nothing does, and that's the problem. There doesn't need to be any suspicion whatsoever. So, there goes the rest of the amendment.

• PC (politically correct), that's 'Newspeak' in Orwell, has almost completely destroyed the 1st amendment. Also, most areas require permits to peaceably assemble for protests, and permits are frequently denied. Petition for redress of the government is a crime now in more than a few districts; it is referred to as 'paper terrorism'.
• The 2nd amendment is under continual attack, from every level of government; and from many private groups. 4 out of 9 supreme court judges just declared against that amendment. Dictators, criminals, and mass murders the world over agree, gun control works.
• Suspension of Posse Comitatus, under Patriot Act, seriously threatens the 3rd amendment. It also removes the main obstacle from the establishment of a military dictatorship. The 'war on drugs', that is Federal funding of CIA drug smugglers, eroded the Posse Comitatus Act; but The Patriot Acts kill it ourtright.
• 4th amendment, see top of post.
• The 5th and 8th amendments were just recently (temporarily) reinstated. Good news there. I expect they will be repealed again before too long.
• Most of the 6th amendment is already on the garbage heap.
• The 7th amendment hasn't been in effect for decades.
• The 9th amendment has been trampled over and over by 'executive orders'.
• The 10th amendment is dead. Feds are dictating to the States every day.

Soon, we will be back to two 'inalienable' rights: The right to pay taxes, and the right to die.
Oh wait, suicide is a crime...forgot about that.
So, you'll have the indisputable right to pay taxes. Wonderful. No politician will ever threaten that right, you can be sure about that.

The most serious danger, however, lies in the ability of one man (the president) to suspend the constitution and declare martial law at a whim, under the 2 Patriot Acts. Basically declare himself 'Dictator of America', as commander in chief of the armed forces.
Think, New Orleans after Katrina, at the national level.
A Michigan state senator recently moved for state wide martial law on the floor of the state senate as a means to 'put an end to civil protests' against state government corruption. The motion was denied; but it is clearly being mulled over over by various scumbag crooks,...I mean politicians.

Friends don't let friends use booleans.
