Does seem a bit of an overkill - I don't seem to remember there being any reports of trouble in the last few years to warrant such actions!
Isn't it a little over the top? I mean - how many other places in the UK will have crowds of people celebrating? And how many of those will have NO police presence whatsoever? Or fences?
Ah well - I'll not be there anyway but will be interested, as ever, to hear how it goes. :)
