I've been thinking again about this justification that a £20,000 fine and six months imprisonment are necessary in case, for example, the musician trails a bare wire through the audience.

Why stop there? A guitarist might see someone in the audience who ran off with his wife and, in fury, garotte him with his E-string. Surely we must make the maximum penalty life imprisonment in case this happens?

There is a fairly serious point here, believe it or not. Suppose some non-musician lays the bare wire of DCMS fame. Can they be prosecuted under the bill? Clearly not. Can they be prosecuted at all? Obviously. So the question is why does the mere fact the person responsible is a musician alter the penalty? And if it doesn't alter the penalty, it cannot logically be used as a jusification of the bill.
