my son has been doing heroin. took his phone away and figured out his password and went through his text messages. i saw his txt between him and his drug dealer. in the messages he says his first and last name. i have also seen my son run out front and go into his car to buy drugs. but didn’t actually see the transaction. but in the text messages my son asks him if he can drive over and sell him heroin. is this enough evidence to get the drug dealer arrested?
