First of all, the attitude of the government is different. In the Philippines, people have the right to kill drug dealers if they refuse to be arrested. The president of the Philippines also paid special attention to drug lords who were arrested and imprisoned, and vigorously eliminated spies from the police. In this case, once you are caught dealing in drugs, even drug addicts or prisoners in prison will be killed. There is also a reward system in the police. Any law enforcement officer who surrenders a drug Lord to the government will receive a bonus of 3 million pesos, making it impossible for the army and the police to deal in drugs. On the other hand, Mexico is not like this. They are really too weak to treat drug lords and allow them to attack police and even kill police and government personnel. In the face of drug lords, Mexico does not even have the death penalty. With such a contrast, it is not difficult to see the difference.
Second, Mexican drugs are all over the world, and the United States is its number one market? The reason why Mexican drug lords are so rampant and dare to confront the police directly by force is because there are powerful arsenals behind them, most of which come from the United States. Moreover, many people in the United States take drugs, most of which are sold to the United States. They are close to such a large drug consumption market in the United States, and they generate such huge profits. Mexican drug dealers will not give up such a huge market.
Third, the problem of corruption within the Mexican government is serious. Faced with such a huge interest temptation, it is easy for officials to collude with drug dealers and profit from each other.
