In your own words provide and objective summary of amendment V. Then describe three present day situations where this law might give a citizen important protections from a potentially abusive government

Basically, the fifth amendment gives you rights in courts to protect yourself against a government that might illegally prosecute you. It prevents the government from making you testify against yourself if you don't want to vote and it provides you with a jury that decides your faith to prevent there being a judge that works for the government. One might be if you're a dissident so the jury protects you. Another is if your property gets taken away then they have to give you payment to make up for it. Another modern thing could be if they wanted to put you on trial for the same offense again and the fifth would protect you from it.
