No, Tyler first scoped out the area in a red shirt and shorts early in the morning. Then, wearing pants and a dark shirt with a flag and an eagle on it before the Charlie Kirk event, he limped a ways down the neighborhood on people's doorbell cams with the rifle shoved down his Right (rear) pant leg (probably partially disassembled) and other parts either under the back of his shirt or in his backpack, when he went up to the roof. Student common areas were on the roof. Very easy.
Tyler quickly reassembled the rifle when he got to the roof but dropped or forgot his screwdriver. After he took the shot, he did not have time to disassemble the rifle again and ran away with it wrapped in a dark towel (a little less than ideal but at least he was not walking with a limp). He had to stash the rifle (assembled) in some trees off campus in order to get away, and he was not able to recovered it later that day despite it having possible fingerprints (and DNA) on it.
I'm seeing a lot of Epistemological Nihilism here. I coined that term years ago, btw.
LHO was a dyslexic misfit who had his Russian-born wife take "Resume" photos (plural) of himself with an Italian Carcaro WWII military rifle and a Smith & Wesson revolver and some Communist literature (for different hostile factions, LOL) at their Oak Cliff neighborhood apartment in Dallas on Neely Street ─ which still exists today, not far from his future boarding house on Beckley St. (two miles from Dealey Plaza and now a museum) and not far from the location where Officer Tippit was shot at 10th and Patton, or the Texas Theater on Jefferson Avenue (where Oswald was captured after sneaking in without paying after shooting Tippit).
Literally no radical groups were interested in hiring Oswald, and in his "resume" photos he comes off as a complete nutter.
The FBI and the Dallas PD did not know that Lee Harvey Oswald had taken a rifle shot at General Ted Walker at his upscale Dallas home, which is today next to an LDS church. Walker was only slightly injured but there were no leads in the case. Walker was a retired Army general and a John Bircher who was against Desegregation, and whom the Kennedies hated, and presumably so did Oswald. The bullet of the future "Patsy," as he called himself later, hit the window pane and deflected just enough to spare Gen. Walker's life. Marina Oswald knew about the Walker shooting, but since her estranged husband wanted to send her back to Russia, she was afraid to talk to the police and her English was rather marginal.
The FBI was not interested in Oswald at all except that as a former defector, they wanted his address on file and Agent James Hosty, who was more interested in investigating Klansmen than cringey Communists, did make one visit to Mrs. Ruth Paine's house in Irving, Texas (ten miles from Dealey Plaza) where Marina was living, to get a current address on Oswald, which prompted a histrionic complaint from Oswald to the FBI, a file which the bureau "lost" after the JFK shooting and Director Hoover started asking questions.
The Dallas PD and the FBI had no leads on the Walker shooting, and they were never interested in Oswald. Later they discovered that Oswald was planning on defecting to Cuba (where the real revolution supposedly was) and had applied for visas at the Soviet and Cuban embassies in Mexico City in late September, 1963. The CIA surveilled the embassies but otherwise they were not interested in Oswald either.
The shots that Oswald took are simply not that remarkable. Oswald was an ex-Marine and a decent shot. Any soldier who could not hit a target the size of a head at less than 100 meters (where you sight your rifle in at) in three tries, I frankly would not want to serve with.
The Charlie Kirk shot was pretty basic for a deer hunter too. The media reported 200 yards at UVU but it was actually 128 Meters or 420 feet (140 yards).
The farthest Kennedy shot was the last one at 81 meters (266 feet), and it was the easiest since it was a straight line with the car, so no right-angle deflection needed, and with the car almost stopped, plus less foliage in the way.
Here is a short video explaining Maximum Point Blank Range. That means meat-on-the-table at less than 300 Meters without a lot of fuss. You just have to sight your high-powered rifle in so that it hits maybe 3 inches high at 100 meters.
