How to scrape data from the Alabama Sex Offender Registry website:

Go to: https://app.alea.gov/Community/wfSexOffenderSearch.aspx
It wasn’t built with webmasters in mind.
You will see a search box. Select each county, one by one, and search. You get a list of all the registrants in the county. Save the page on your hard drive. Write a program that extracts the URL of each registrant. Write a program or BATCH or bash file that uses wget or curl to download each of these. You will need a program that extract the data from each individual detail page. You will also need a program that downloads the photos. The URL of each photograph contains an ampersand, and it may need to be escaped out with a backslash in your download program.

If they don’t like it, why don’t they offer a data download link?
