In fact it may well prevent a repeat of the GLA attack, but for security reasons it is not really appropriate to say how. Just be glad that something is being done with consideration for your safety and security, RAFAT.
No it wouldn't prevent a repeat. Obviously I'm not going to say how, but any fool could work it out in about 10 seconds flat! So as I said above, it achieves nothing and inconveniences everyone.
