Our rights come from God. If our rights do not come from God, the government is free to do as it pleases, because then everything is subjective.
I am willing to live in danger if it means that I am free. If that means I must accept a minuscule chance of being shot wherever I go, so be it. I will not give up any essential liberty to secure some temporary safety.
