恐怖活动犯罪给世界的和平、稳定造成了巨大的威胁，被称为“21世纪的政治瘟疫”。我国也深受恐怖活动犯罪之害，近年来我国恐怖犯罪有愈演愈烈之势，给国家和人民带来了巨大的损失。针对我国反恐的严峻形势，有必要从法律的角度来对于恐怖活动犯罪进行研究。本文以北京天安门“10.28”暴力恐怖犯罪作为研究恐怖犯罪的出发点来对于恐怖活动犯罪进行讨论。依据北京天安门“10.28”暴力恐怖案件的基本案情和裁判要旨对该案件所涉及的定罪、量刑、共犯、立法完善等法理问题进行分析。首先，由于我国恐怖活动犯罪立法体制的原因，当发生恐怖活动犯罪时需要对犯罪分子以组织、领导、参加恐怖组织罪和其他具体犯罪进行并罚。本案的具体恐怖行为是以以危险方法危害公共安全罪定罪处罚的。因此应当对以危险方法危害公共安全罪进行分析，并得出该犯罪需具备以下特质：（1）就危险性而言，需具备与故意杀人、故意伤害相当的危险性，才能构成本罪；（2）就侵害对象而言，需要侵害多人或不特定人的生命、健康或重大财产损失；（3）就造成的危害后果而言，实施该犯罪极有可能造成严重的危害后果，或者已经造成了严重危害后果。通过对本案的分析得出玉山江.吾许而等被告人成立以危险方法危害公共安全罪。本案对玉山江.吾许而等人以组织、领导、参加恐怖组织罪与以危险方法危害公共罪数罪并罚主要是基于我国刑法第120条的规定，但是这种立法模式同样存在问题，如容易遗漏一些犯罪，难以突出恐怖活动犯罪的特点等。建议设立单独的恐怖活动行为犯罪罪名，以弥补现行立法缺陷。其次，由于北京天安门10.28暴力恐怖活动是由多人组织、策划实施的，玉山江.吾许而等人并没有参与实施该暴恐事件的实行行为，而是在案发后才被警方抓获的。因此从共同犯罪的角度来分析本案是有必要的。从共犯的构成要件分析，结合本案案情，得出玉山江.吾许而等人构成共同犯罪，并从主犯、从犯的刑事责任方面分析了各被告人的责任承担问题，从共同犯罪这一方面验证了对本案各被告人的定罪量刑是合理的。再次，本案对玉山江.吾许而等三人适用了死刑，笔者从我国现阶段的死刑形势政策、法律依据和各被告人的犯罪情节等方面对于玉山江.吾许而等三人适用死刑的合理性。最后，从立法完善方面和恐怖犯罪适用宽严相济刑事政策问题进行了讨论。从恐怖活动犯罪的立法体制和适用财产刑方面对恐怖活动犯罪的立法完善进行了分析。宽严相济作为我国基本的刑事政策应当在恐怖活动犯罪中予以贯彻，本文在最后讨论了宽严相济的刑事政策是如何在恐怖活动犯罪的立法、司法等方面加以体现的。
