Lets not blow this out of proportions.... No-one got injured, or even a punch thrown. In fact Millwall behaved worse last time we played them - climbing over the netting, tipping over the barriers and queue jumping at the station etc.
I think they've taken it to far haven't they? Not really my thing but a bit of singing, maybe a drum and display is all well and good but from what I have seen in terms of comments from your own fans and their behavior before and during the game it's pretty diabolical. Charging around, throwing...
A lot of what if's but the reality is it was contained and policed and no Brighton fans got injured (just Palace ironically...)
You're actually breaking the law if you send someone away or detain someone for being in a town without a match ticket, unless you can prove they are there to cause...
