How much will it cost me to hire a lawyer to defend me?

Can I really get in trouble for what is on my Facebook or MySpace page?

If I am driving a vehicle and an officer stops me and asks me to do a field sobriety test and/or provide a breath or blood sample, do I have to take the test?

If an officer knocks on my door and requests to search my residence do I have to let him in?

Should I hire a lawyer if I am charged with a criminal offense?

Do I have to speak with an officer if he wants to ask me questions?

What do I do if I am stopped for a routine traffic violation and an officer asks to search my vehicle or person?
