Why did the marchers trun around the second time they gathered at Edmund Pettus Bridge

The first time the marchers were at the bridge, they were brutally beaten by police. As a result of this, a judge was planning on a court order that kept police from interfering with a protest if it happens to be peaceful (which is what MLK’s was). However, until the court order took effect, there was a restraining order placed on marching the week leading up to the court order. Thus, MLK decided not to march in order to not violate the restraining order.
