Adding on to @infiniteflight_17 , please recognize at very busy airports at peak times, controllers eyes may be on the opposite end of the airport dealing with something else, such as a go around, or even another report. One time I had to deal with 3 reports in a span of 10 seconds (although that is quite rare). Many reportable offenses can take place in a matter of seconds, and we need to be 100% certain a report is deserved before we send it. If we only catch the last seconds or the aftermath of the offense, we can’t beyond a reasonable doubt say something happened.
Also at a quick glance, it’s easy to look at it and not know whether it was you, or another pilot, who committed the offense. Who flew through who, or who taxis through who, is always something that can come in to question. Obviously, we’d hate to report the wrong guy (such as yourself) thinking that you were the one that did it.
However we do personally apologize that this happened. Obviously we try to maintain the best standard, but unfortunately, like explained above, certain situations may fall through the cracks. I’m truly sorry, and I truly hope such event never happens again.
