What is With This?

Just west of the 110 Freeway, adjacent to Downtown Los Angeles, this chain link fence cage was recently installed, it seems, in response to the tent community that had been set up there and had been growing over the months. The cage is fenced on all sides including the top, blocking off a good 1/2 of the sidewalk.  This is an offensive and truly bizarre technique for addressing the issue.  We can use positive and proactive- rather than reactive and unfriendly - ways to design our streets.
