Well you see that's not entirely true about America. I just brought up the gun point because it is one of our freedoms that we have and we really enjoy expressing. Well you see here, we don't have censorship laws unless it causes a panic like yelling bomb on an airplane, some people use it to spread hate and bigotry which sucks, but there's always people that don't give those types the time of day because it's hatred and not good. Other things that we have are the 4th amendment which states

The Fourth Amendment of the U.S. Constitution provides, "[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly ...

which is actually really great being that they can't just enter your home or search you or your car without a warrant or probable cause. If they do the evidence they find can be thrown out in court and everything else associated with that evidence is also thrown out.

We also have The 5th amendment which States

The Fifth Amendment of the U.S. Constitution provides, "No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a grand jury, except in cases arising in the land or naval forces, or in the militia, when in actual service in time of war or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."

so you can't self incriminate, nor can you be tried again for the same crime if the they fail to get a guilty verdict
