I should explain that "rolling gun battle" is an American journalist's cliche for when criminals shoot at each other from moving cars. Obviously the potential for hitting the innocent is enormous.

Such a thing occurred in front of my grocery store yesterday. One passerby was injured, we don't know how seriously. Both cars crashed, something which comes as no surprise in a neighborhood of old, narrow and curving streets. The police rounded up the participants.

About "feeling lost, hatred, and depression": this list suffers from a lack of parallelism. There might not be a rule about parallelism, but it contributes to grace and smoothness. (I learned about parallelism in high school English class.) As someone pointed out, changing "lost" to "loss" would create three nouns, a nice case of parallelism.

As it stands, the sentence is so awkward that I'm sure the t on lost was a typo, not a conscious choice.
