4月29日，一名北京市民发帖吐槽，他在乘坐公交车时发现车窗已经被螺丝钉定死无法打开，一旦发生火情或其他突发情况，封闭式车窗可能会影响紧急逃生。 该市民表示不知道公交集团这么做的原因，而据我们了解，这是中共为了防止有人在公交车上撒传单，而采取的一种不惜把乘客安全置于危险之中的极端措施。这种情况已经持续很长时间了，最早可以追溯到2012年。
On April 29, a Beijing resident posted a complaint online regarding a safety hazard on city buses. The commuter noticed that the bus windows had been permanently bolted shut with screws, making them impossible to open. This raises serious concerns that in the event of a fire or other emergencies, the sealed windows would severely hinder emergency escapes.
While the resident expressed confusion over the bus group’s motives, it is understood that this is an extreme security measure implemented by the authorities. The goal is to prevent petitioners from throwing leaflets out of bus windows, a tactic that prioritizes political control over passenger safety. This practice is not new; it has been in place for a long time, with its origins tracing back as far as 2012.
