You don't get asylum because of local crime/safety. Also, you are supposed make the claim for asylum at the first country (Mexico) for your claim to hold up.

So most of these recent claims can and should be immediately rejected. There was brief window where Obama's DOJ changed policy and allowed granting asylum for local criminal problems (non-state oppression). Trump's DOJ changed the asylum policy, returning to international norms.

So unless an alien is fleeing state oppression and they have tried to get asylum at the nearest/adjacent non-conflict country, they have no grounds for receiving asylum in the USA.
