Answer:
The 4th amendment protects people from unwarranted searches or seizures of that person's property among other things
The 5th Amendment declares that " no person should be held to answere for a capital or infamous crime except upon indictment of a grand jury" so it helps people alot.
The 6th Amendment guarantees a person a speedy and public trial. I belive the speed trial because of the people's right to go free if found innocent and so the goverment cannt imprison a person for an outrageous amount of time, as well as so their defense can be aduquility prepared. The public to make sure it's a fair and just trial.
This does not prevent law enforcement from doing a good job, it nearly protects a person's right to live free. As well as the right to not live in a police state, where the goverment does whatever they want without boundaries.
