Ohhhh....I don't live in the USA or know what Griffith Park is, but I cetainly know that burning public stuff is wrong.
I saw a random flash of fire in Queens Park (a local park in my area). I was like "Eh?"
About the complaining, I hate that for now on, in NZ, you have to be 18 to buy fireworks. It was formerly 14, and you can't buy Sparklers individually. It's all because of everyone making sparkler bombs and launching fireworks at each other. [edit]
