Copy Protected General Assembly Transcripts?

Here you can access transcripts of the Illinois House and Senate floor debates going back to 1997 1971 (change noted here). The transcripts are in PDF format. On occasion I include an excerpt from a transcript in my work. But I can’t copy and paste from the PDFs because they are set to prohibit copying. Check it out for yourself. Why is the copy function blocked on the PDF transcript files?
