Wrong, wrong, wrong, and wrong.
Leaving aside that this is UK news and the UK doesn't have the 5th Amendment, protection from being forced to testify against yourself is not based on this ideology you assume it is where your memory would be protected. You misunderstand the entire reason for the right. The reason for the right is because of the long history of forced confessions. History teaches that when the police interrogate them long enough and hard enough they can get them to "confess" to almost anything; even heinous crimes carrying the death penalty. This can be achieved without traditional torture, with just hard questioning and lack of sleep. Because of the physical power the police hold over a person who has been arrested, this is a pervasive problem in places without these protections, including historical England.
But the 5th Amendment doesn't protect physical facts, and it doesn't protect your memory; it protects you from testifying about your memory. If your memory could be read by doctors using a harmless mind-reading machine, that would be allowed, because it would be physical evidence, not testimony that might have been compelled.
Another problem with compelled testimony is where they attempt to accuse a person of lying in their claim of innocence, even before it is established that they are guilty. Prosecutors are very good at that; finding some innocent detail you remember wrong, or perceived differently than witnesses, and then using that to "prove" you're lying. And your denial contains lies, that is almost the same as a confession in the hands of a skilled prosecutor.
Another example of what can be compelled is the location of a key to safe, or the combination to a safe; assuming the police have a warrant, no physical evidence is protected by the 5th Amendment, including things like the location of a key. The safe is physical evidence, not testimony. And the location of the key is an objective physical fact that is not prone to the type of abuse that a compelled confession is.
And you would send a judge to freakin' prison over your lack of understanding of the very rights you claim to value, yet somehow know nothing about. You even then somehow manage to work in a false accusation of terrorism. There is nothing basic about your ass-hattery; you're a first class champion ass-hat!
