All good points and I agree, i think they'll get on top of it sooner rather than later though.
West 'Am can't be doing with this sort of negative PR in 2016, a bit of HD CCTV and a few banning orders will keep the trouble out of the stadium and onto the streets at least. Not that it's any better out on the streets, but at that point I don't think you can do a lot about it.
i've been in police cordons (mainly at the Lane ofc) in the 90s, 00s and this decade as well at various ages, it's never going to be eliminated. What has improved over time is the efficiency of the policing, but it's taken quite a few incidents of trouble for that improvement to happen. Last season's League Cup tie at Tottenham away was probably the 3rd or 4th worst i've experienced and even then I couldn't fault the policing.
Common sense should prevail, don't take your kid to certain games. The Chelsea dad with his 8yo daughter and the coins; it's terrible but i'd question his common sense quite frankly.
