Never use your real name online ....... for anything.
I rarely use my real name, even with my friends, they don't need to know.
Never interact with the police unless arrested, and then only with a lawyer present. No chat, no friendly questions and answers, don't let them enter your home without a search warrant, force them to either arrest you or walk away.
When arrested and questioned under caution, with your lawyer, be vague, be evasive, I don't remember that, I'm not sure I was there. If you admit to being there, they are half way to proving you guilty.
