Ron Paul abstained from voting on the Protect America Act in 2007 which was the genesis for much of the PRISM program. Not a NO vote, abstained.

at 3-4, OWLY is fantastic. published by Top Shelf
Marvel put out a line of comics called MARVEL ADVENTURES with much more "kid appropriate" comics with the big icons of the Marvel U. They can be found in the digest sized format.

Chris Eliopolous also put out a marvel comic based on Franklin Richards of Fantastic Four fame, it reads like Calvin and Hobbes with Franklin as Calvin and H.E.R.B.I.E. the robot from the 70's FF cartoon as his Hobbes. Delightful. digest format as well.

Your local comic shop should also have either Essential Collections or Marvel Masterwork tradepaperback collections of the early Marvel Comics of the 60's. Amazing Spider-man 1-20 for $20 in black and white. or 1-10 in color. might be a little early for a lot of that stuff.

Fantagraphics is publishing the complete Carl Barks library right now. vol. 2 is due out shortly.

Fantagraphics is also publishing the Complete Peanuts. 2 years per volume. They are in the early '80's right now.

Lastly, use your local library if you can. You'd be amazed at how much is being purchased by librarians right now to keep kids reading. 741.5 is your dewey decimal. Also, your kids/teen room will usually just have a whole shelf of graphic novels now a days. free looking.

Lastly part two. Let your kid be a kid as long as possible. Don't force violence at them before they're ready. Most of the above recommendations are way over the head of a 3 year old. Let alone an 8 year old.

Enjoy. my now 16 and 13 year olds have 2 bookshelves of classic Marvel and DC books. They're also huge fans of Bone and Mouseguard and other great age appropriate stuff...
