a person who has committed a crime
Crime, among others, is:
an action or omission that constitutes an offense that may be prosecutedby the state and is punishable by law
or
an action or activity that, although not illegal, is considered to be evil, shameful, or wrong
It is clear, indeed very clear.
Criminals may be those who have acted with evil or wrong intention, whether the Laws is enforceable.
And who are those criminals?
Those are people who steal the State's wealth, and pretending to be the Guardian of the people
Those who have taken someone else life and openly claiming that the deceased suicided.
Those who have twisted and spin truth and preventing truth from seeing the lights.
Ask yourself, are you one of them..
