I have to point out the obvious, which is that there has been nearly 2 centuries of people pumping money into propaganda to convince people that the Constitution and Bill of Rights means what they want to mean, not what was intended originally. That people continue believing increasing levels of bullshit is not a surprise, incremental change is how things always happen. Propaganda and Sociology are not "new" sciences by any stretch of the imagination, but also not something normal people get taught about.
So read some history and figure out what was intended by the 5th, and you will find that it does not match the currently used "spun" definition. I'll give you an easy one, which history will verify repeatedly. If you need citation start at the Federalist papers, Biographies, and court documents from the US and England.
At the time of the Revolution, British soldiers were searching people's houses for things like diaries. If you had the wrong shit written in yours, you were executed and sometimes sent to a nice London jail. Vague writings were the best, because a person disliked could easily be charged with a crime based on their own words with invented outcomes. Speculative thought crimes like "he was thinking treason" were as common as false allegations, "see he was mad at the Smithers so killed that guy everyone thought was mauled by the bear". It was all about who disliked you and what dirt they could find on you (nothing new there). The limitations in the Constitution were intended to prevent the Government or an agent from searching your crap and using it to possibly invent a crime based on their findings. The part about "speech" is a newly formed pile of shit which people are gullible and ignorant enough to believe.
History will show you the "meaning" of all of the wording in the Constitution and Bill of Rights. Contrary to bullshitter and con-artists statements, there is no ambiguity or accidental language in the documents. None, zero, zip, nada, nill, null, etc.. etc...
