There's a search engine called "feefiefoefirm" that lets you search the websites of all US law firms for information. It also offers the option of search law firm websites in the UK, Australia, Canada, New Zealand, Singapore, Ireland and South Africa. You can use it to search for legal experts, law firm bulletins, articles, press releases etc. and you can set date limits from the past 24 hours to the past five years. For example, a quick search for "Tasers" in the "past year" got 22 results, including some interesting articles and blogposts about the legal aspects of taser use.
