If only you could use your eyes. There were never any saws only scallop edged plates designed to keep people from being able to grab between the buoys and slide through. The nets can also be understood to be barriers In place to stop people from diving under the bouys. Without seeing a picture of the nets, I cannot make any claims to their danger because they could be a fine mesh or they could be a rope net. One would be stubstantially more dangerous than the other.

There’s an easy way to avoid the murder buoy saws called “stop crossing the border illegally”.
