The number of protectively marked PDF's on the web is staggering, try these:

Try other protective markings from other countries to see more. Clearly searching for "Top Secret" will incur a lot of separating chaff from wheat. The biggest surprise is the number of government protectively marked papers that are searchable - these are typically papers that are being passed between departments and the paper is being mis handled down the line of recipients.

I've seen a lot of misuse of confidentially marked papers in commercial organisations - I see them regularly sitting on a printer in open plan offices. Largely because staff working for big financial companies do not have information security drilled into them. They have to sit computer based training tests regularly - but there is little comeback for employees who regularly flout the rules.
