In other news the Pope is Catholic.
They run this one every year. The replies on their twitter feed are hilarious. People owning the DM.
From an islamic prospective though, some of the stuff shown in the pictures is incorrect.
For example, you can see live animals at the scene where other dead animals are. This is against the conditions for halal sacrifice. Also you see a lot of dumbass attempts to tackle animals, causing them distress. Unfortunately at this time of year there is a shortage of trained butchers/slaughterers, so cowboys and amatuers advertise their services, hoping to make a quick buck.
On top of all that, a lot of people are filthy pigs in general. Look at the areas where these animals are being sacrificed. Streets, courtyards - it's going to spread disease. I can't say for other countries, but in urban Pakistan the mess in some neighbourhoods after this festival is a disgrace. This is all down to bad governance.
I've seen the sacrifices done in our village and they do it away from other animals, they wash away the blood and bury the insides etc. They don't want to attract wild animals and stuff like that.
