you try to stay -- phoenix graffiti. * it's not broken. >> do you write any flickr warrants? >> i don't use flickr. instagram is huge right now. >> they went away from flickr. >> they came and went pretty fast. i'm sure there's some still out there, but our kids in phoenix don't really use it. >> it was good because you can put in multiple tags. if you put in the right key words and put a space in between them you can figure out all kinds of crews, monikers, and where they're tagging to, what cities. >> yeah, i've never had to do flickr yet, but insta gram, facebook, youtube, those i have. any other questions? i hope something you got from me you can learn. if you didn't hear everything you wanted to hear, call me. like i said, i don't care what time it is. if it's about graffiti, like i said, i'm passionate about it. i'll help you out with anything. if you need to write a search warrant i'll help you write the damn search warrant as long as you take someone off the street. good luck and be safe.
