Benefits of security agreement.

Firstly nonrelated, been ages since ive been on here. Been studying other things actually, marc stevens and cop watch hawaii, etc. Good to be back. looking to finally set myself as a spc in a couple of days, though trying to recall the benefits of the security agreement?(or spc benefits in general) mainly for legal situations like being charged with a felony. How could it help? basically a victimless crime from years ago is on me
