The general rule is you cannot search their electronic devices without a warrant unless the person gives permission, unless you can prove , beyond doubt, that the search is required to save a life in immediate threat. You are governed by federal law first, state law second, and it is usually a mixture of the two. being a trouble maker/drug use seems to me to not fall into the category of a life in immediate threat. Do it the right way and get a warrant. You will not be in the wrong if you get a warrant, but you could be open to having anything you find on that phone being inadmissible if you just search it because you arrested a person for what would be deemed a misdemeanor offense.

If the phone is locked, you will need a warrant to open it and phone manufacturers are reluctant (read adamantly against) assisting in opening a phone citing privacy as the software can be used to open other phones.

I think even if you get a warrant, you cannot compel a person to open their phone. With the warrant, you could take it and search it as far as your were capable, but you couldn&#39;t force the owner to unlock it.

It’s a definite, ‘maybe’. But generally, the rules for searching a phone without a warrant about the same as searching the pockets without a warrant. <br /><br />The scenario is too vague to give a definitive yes/no.

Because you had no cause for the arrest, any search subsequent to arrest is also invalid.<br /><br />Merely being a &quot;known troublemaker&quot; does not provide probable cause, or even reasonable suspicion, without other clearly defined and articulable actions.
