Well, for the recording, I can put a SD Card, up to 16GB in it, so no problem.
The thing of recording ppl, well...what about Spotters on public events, who taking pictures and recording videos all the time. I've never heared, that they ask everyone for that. I know, the german laws are strict with it...they HAVE to ask, if there isn't a group with more than 5 ppl. But if its on a public event, or a convention, everyone is taking pictures/videos...so, I think its ok. Otherwise they would mention it (At least to the spotters, so I wouldn't use that material anyway).
Just btw. I never used that material yet. Because of my chaotic jumping around, there are only a few good scenes ^^° I also like that for myself...as some memories. As I said, the thing with that attacker...he tried to pull my ear off and it was painful >.< I so wish I would have had a picture of him...
