Certainly could. But odds are they've got copies of everything already. Police are usually intelligent enough to include ALL of those things in search warrants, and grab everything at once just so that people DON'T get a chance to destroy evidence. You can be pretty assured that if they've taken the step of seizing your computer, then they've already got cell phone dumps, email dumps, bank statements, and the last server backup of the website from your webhost. Deleting at this point is likely useless, and only serves to make you look WORSE in front of a jury (why destroy those things if nothing was wrong?).
Without charges, there's no arraignment. No arraignment means no opportunity for you to request a public defender. So if you want an attorney before you get charged, it'll need to be one that you select and pay for.2. Am I allowed appointed representation without charges being filed?
Yep. It can. Start saving for an attorney ASAP and hope that the state needs some time to bring any formal charges.The way I understand it, the investigation can remain open forever.
