There's law and there's human right, if we don't know what the law says then it may be abused or used against us, some people are not know what their rights are, how will they be able to fight for them, but the governments will always uses that same law to find us each time we are guilty, they are always found hiding under the same law because they know what it says, how to dodge some aspects they are guilty of and project the ones they know is part of their right to claim, henceforth we should also speak out our rights and fight for them when necessary.
Knowledge is power indeed, and that also goes further to tell us how the importance of education is on individuals because with the knowledge of your rights as a person, anybody can easily abuse you even when you are on your right because you don't know, so ignorance is indeed a big hindrance to our freedom, speaking and fighting for our right is very necessary and just as I ooh ted out in the earlier comments, one doesn't necessarily need to know everything concerning the entire laws but as a citizen, it is important to at least know your fundamental rights.
Just like a trend that is happening in my country, where policemen just demand to search a suspect phone, meanwhile, the law gives citizens the right to privacy over mobile phones and unless with a warrant duly signed by a court to search the phone only then you can allow police to have access to your phone.
But if you don't have this information in the first place, how then do you intend to enforce it at some point if the need arise?
