Supposedly Illegal Fireworks Sold At Walmart?

Well I just looked up the law in my state, and apparently, all fireworks besides sparklers are ILLEGAL, and you need to be 16 just to buy sparklers?? This makes no sense to me, since I have been buying party poppers, snappers, and sparklers from general stores down the street from me since I was about 9, and have never had anyone tell me it was illegal or I couldn't buy it. Not only that, but I remember seeing tons of boxes of roman candles, fountains, and other fireworks at Walmart, especially around July 4th. Can someone explain this to me? Is the place I looked at waaaay outdated, or just filled with wrong info? Is the law just not being enforced? I live in CT, if that helps.
