Absolutely not. If you are caught taping, thus violating the contract you entered when purchasing the ticket/entering the facility, all the venue can do is void said contract and ask you to leave. Never give them anything. If I was caught (still hasnt happened, knock wood), I would ask that my gear be checked in/put in a locked room until the performance was over and enjoy the rest, if given the option. Otherwise, take your lumps and leave. Perhaps put the gear in a car and try to re-enter to see the rest of the performance.
