There are only two choices. One is to have a wall recognizing its true purpose.The other is to tear down the wall.So far, I have yet to see the governor, senators or representatives of California demanding the wall between Tijuana and San Diego be torn down.Andy Beiniks Charlton 1) The city of Schenectady does have at least one small sidewalk-sized snow machine, which it uses to clear certain city and county walks, sometimes.2) When my neighbors and I clear our walks on Guilderland Avenue, the city fills them back in.Snow plows travel up and down the street, usually well over the speed limit, and the very heavy snow and slush are thrown over the snowbanks, onto our sidewalks.Usually, the stuff freezes before we can get back out to re-shovel (not that it matters, the plows come by again after we do), but even when it doesn’t, the mixture from the streets is so heavy it isn’t worth trying to shovel it again, unless you have a physical therapist on speed dial.So the city has the capability of clearing the sidewalks.It really needs to do so after the homeowner has already cleared a path, and the city fills it back up again — as it has been doing for the more than 30 years I’ve lived on Guilderland Avenue.Kurt C.

Andrew Cuomo’s press conference for Sunday, Oct. 18EDITORIAL: Thruway tax unfair to working motorists Plows put the snow back on sidewalksSara Foss’ Feb. 25 column was very interesting, regarding municipalities’ policy of clearing sidewalks.I’d like to add two things to her commentary: Categories: Letters to the Editor, OpinionWall is designed to delay, not defeatThe opinion piece by Ieva Jusionyte on the effectiveness of the border wall, published on Feb. 24 shows a complete lack of understanding as to what a wall is supposed to accomplish.He states, “…no matter the design, the fence does not deter unauthorized migrants.” The actual purpose of protective walls is to slow an intruder until a reaction force can arrive. Why does a bank vault have thick concrete walls and a thick door? It’s to slow down someone trying to break in until the police arrive.If the police aren’t going to bother showing up, you could take a jackhammer to the walls of the bank branches on Route 50 in Glenville on a Sunday to leisurely break in and take the contents of the vaults.So-called technological solutions such as drones, motion detectors and video cameras really only work in conjunction with a physical barrier that establishes a final protective barrier. If walls and fences are that ineffective, why does the military put up walls and fences around their compounds in Afghanistan and Iraq?If you choose to believe Ieva Jusionyte and other critics of the effectiveness of a wall, then you would believe that the military wasted a lot of time, effort and money building walls and fences in Afghanistan and Iraq to protect our forces.
