Why has direct action increased?

the the reason for why direct action has been on the increase in recent years could be down to a couple of reasons. firstly because if you campaign outside the normal decision making process by targeting the public and the media which will give you a huge amount of leverage on the political agenda take for example fathers for justice dressing up as superheros or the recent London riots over the increase in tuition fees. this could be because these outsider pressure group have not access point into the political agenda as other pressure groups do for example the National Farmers Union who lobby in parliament and help parliament when making laws on agriculture and who help in times of crisis like the foot and mouth out break. So this is the only way outsider pressure groups can make there voice heard. also these pressure groups do not have the organisation or the infra structure to raise the vast amounts of money that that insider groups have at there disposal to lobby in parliament.
